Protecting yourself against poison attacks

Reliable Networks on December 5, 2024

Protecting yourself against poison attacks

Data poisoning by way of logic corruption, data manipulation and data injection happen when the attacker finds a way to access your data set. The kind of poison attack varies depending on the level of access the attacker is able to achieve Here’s what you can do to ensure such access is prevented.

  1. The data poisoning attacks discussed above adversely affect your IT system’s machine learning capabilities. So, the first logical step would be to invest in a good machine learning malware detection tool. These tools are different from the typical anti-malware tools you get in the market and are specifically designed to prevent machine learning capability poisoning.
  2. Always follow general IT security best practices such as-

    1. Training your employees to identify spam, phishing attempts, and possible malware attacks
    2. Following good password hygiene, which means never sharing passwords and only using passwords that meet the required security standards
    3. Having a powerful IT audit process, tracking and version control tools, so as to thwart any possible insider attacks
    4. Ensuring the physical security of your IT systems by way of biometric access, CCTV systems, etc.,

Whether it is data poisoning or a malware attack, you certainly don’t have the time to look into all the security aspects yourself. Even if you happen to have an in-house IT team, this 24/7 monitoring may be too much for them to handle as you grow. Consider bringing a reputed MSP on board to help you with this, so you can focus on your business, worry-free, while they ensure your data is safe.

Cyber Experts Say You Should Use These Best Practices for Event Logging

Chris Provencher on December 5, 2024

Today’s businesses are no stranger to the word cybersecurity. They are facing a growing wave of cyberattacks. These come from ransomware to sophisticated phishing schemes. How do you stand ahead of these threats? A strong cybersecurity strategy is essential. One crucial component of this strategy is event logging. It’s one that not every business owner is aware of.

Think of event logging as a digital detective. What does tracking activities and events across your IT systems do? It helps you spot potential security breaches and respond swiftly. As your managed IT service provider, we’re committed to helping you. We can help you understand the importance of event logging as well as how to put in place best practices to safeguard your network.

What Is Event Logging?

Event logging is the act of tracking all events that happen within your IT systems. “Event” can be many different things, such as:

  • Login attempts
  • File access
  • Software installs
  • Network traffic
  • Denial of access
  • System changes
  • And many others

Event logging means to track all these and add a time stamp. This provides a robust picture of what is going on in your IT ecosystem. It’s through that ongoing picture that you can detect and respond to threats promptly.

Why is it critical to track and log all these events?

  • Detect suspicious activity by monitoring user behavior and system events.
  • Respond quickly to incidents by providing a clear record of what happened in a breach.
  • Meet regulations that require businesses to maintain accurate records of system activities.

Best Practices to Use Event Logging Effectively

Event logging is most effective when you follow best practices. Here are some standard guidelines to follow. These are helpful if you’re just starting out as well as for those improving existing event-logging processes.

Log What Matters Most

Let’s be honest: You don’t need to track every digital footstep.  Logging every single action on your network can create a mountain of data that’s hard to sift through. Instead, focus on the events that truly matter. These are those that can reveal security breaches and compliance risks.

The most important things to log are:

  • Logins and Logouts: Keep tabs on who’s accessing your systems and when. This includes failed attempts, password changes, and new user accounts.
  • Accessing Sensitive Data: Track who’s peeking at your most valuable information. Logging file and database access helps spot unauthorized snooping.
  • System Changes: Keep a record of any changes to your system. Including software installations, configuration tweaks, and system updates. This helps you stay on top of changes and identify potential backdoors.

Event logging is much more manageable when you start with the most critical areas. This also makes it easier for small businesses.

Centralize Your Logs

Imagine trying to solve a puzzle with pieces scattered across different rooms. It’s chaos! That is what happens when you try to work with several logs for different devices and systems. Centralizing your logs is a game-changer. A Security Information and Event Management (SIEM) gathers logs in one place. This includes those from various devices, servers, and applications.

This makes it easier to:

  • Spot patterns: Connect the dots between suspicious activities across different systems.
  • Respond faster: Have all the evidence you need at your fingertips. This is helpful when an incident strikes.
  • Get a complete picture: See your network as a whole. This makes it easier to identify vulnerabilities.

Ensure Logs Are Tamper-Proof

It’s important to protect your event logs! Attackers love to cover their tracks by deleting or altering logs. That’s why it’s vital to make your logs tamper-proof.

Here are some tips:

  • Encrypt your logs: Lock them down with encryption. This makes them unreadable to unauthorized eyes.
  • Use WORM storage: Once a log is written, it’s locked in place, preventing changes or deletions.
  • Use strong access controls: Limit who can see and change your logs to trusted personnel only.

Tamper-proof logs provide an accurate record of events even if a breach occurs. They also keep the bad guys from seeing all your system activity tracking.

Establish Log Retention Policies

Keeping logs forever isn’t practical (or always necessary). But deleting them too soon can be risky, too. That’s why you need clear log retention policies. 

Here are some things to consider:

  • Compliance requirements: Some industries have specific rules about how long to keep logs.
  • Business needs: How long do you need logs to investigate incidents or for auditing?
  • Storage capacity: Make sure your log retention policy doesn’t overwhelm your storage.

Strike the right balance with retention. You want to ensure you have the data you need without sacrificing performance.

Check Logs Regularly

Event logging is only as good as your ability to use it. Don’t “set and forget” your logs. You should check them regularly. This helps you spot anomalies and identify suspicious patterns. It also helps you respond to threats before they cause serious damage. Use security software to help automate this process.

Here’s how to do it effectively:

  • Set up automated alerts: Get notified immediately of critical events. Such as failed logins or unauthorized access.
  • Perform periodic reviews: Dive into your logs regularly. Look for patterns that might show a threat.
  • Correlate events: Use your SIEM to connect the dots between different activities. It can reveal more complex attacks.

Poison Attacks: A quick overview

Reliable Networks on November 28, 2024

Poison Attacks: A quick overview

Smart technology is everywhere. Not just in our offices, but even in our day-to-day lives with tools like Google Home and Alexa becoming a commonplace. With technology becoming smarter every minute, the risks are increasing by the minute as well. Cybercriminals are finding new ways to corrupt our IT networks to disrupt our businesses, hold our data hostage and even clear our personal bank accounts. Some of the more overt, commonly known acts of cybercrime include hacking, phishing, and ransomware attacks. This blog discusses a lesser-known cybercrime–Poison attacks.

What are Poison attacks
Poison attacks are attacks on the ability of the system to make smart decisions. Think about this. How do systems make intelligent decisions? Based on the training or data they receive. This data is used to hone the artificial intelligence of the system to help make smart decisions. Poison attacks mess the very base–the training data set. Poison attacks basically skew the system’s data model in such a way that the output is no longer as intended. They create a new normal for everything. Poison attacks are primarily backdoor attacks. In a backdoor poison attack, the attacker creates a loophole in the core data rule and trains the system to adhere to that rule so it can be exploited at a later time. For example, let’s say, the access control for a particular file is set such that it will allow only those beyond the VP level to view the data. If someone changes the main parameter to include manager level in there, the core data set is violated and the system will not detect an intrusion by someone at the manager level, even if they log in with their credentials.

Unlike Ransomware, poison attacks don’t make much noise but cause far more damage as they can go undetected for a longer time. Follow our blog next week as we discuss the 3 common types of poison attacks

Watch out for these poison attacks!
Poison hamper the ability of the system to make smart decisions by disturbing the very core data set that is used to make a decision. Poison attack methodologies typically fall into one of the following 3 categories.

  • Logic corruption
  • Data manipulation
  • Data injection

Logic corruption
In logic corruption, the attacker changes the basic logic used to make the system arrive at the output. It essentially changes the way the system learns, applies new rules and corrupts the system to do whatever the attacker wants.

Data manipulation
In data manipulation, as the name suggests, the attacker manipulates the data to extend data boundaries that result in backdoor entries that can be exploited later. Unlike logic corruption, the attacker doesn’t have access to the logic, so they work with the existing rule and push data boundaries further with a view to accommodate them later.

Data injection
In data injection, the attacker inserts fake data into the actual data set to skew the data model and ultimately weaken the outcome. The weakened outcome then serves as an easy entryway for the attacker into the victim’s system.

Employee training and Cybersecurity

Reliable Networks on November 21, 2024

Employee training & Cybersecurity

Employee training will form a big part of the cybersecurity initiative that you will take on as an organization. You need to train your employees to identify and respond correctly to cyberthreats. Here are some employee training best practices that you can make a part of your cybersecurity training program.

Create an IT policy handbook
Make sure you have a handbook of your IT policy that you share with every new employee, regardless of their position in the company. This IT policy handbook must be provided to everyone–right from the CEO to the newest intern in your organization. Also, ensure this handbook is consistently updated. IT is evolving at great speed and your handbook must keep up

Make cybersecurity training a part of your official training initiatives
Cybersecurity training should be a part of your corporate training initiatives for all new employees. You can also conduct refresher sessions once in a while to ensure your existing employees are up-to-date on the latest cyberthreats. At the end of the training session, conduct tests, mock drills, certification exams. Good training includes assessment. Provide follow up training for those who need it. This strong emphasis on training will ensure your employees take cybersecurity seriously.

Day zero alerts
As discussed, the cybercrime landscape is constantly evolving. Every day, cybercriminals are finding new vulnerabilities to exploit, and new methods to steal your data or to hack into your system. Day zero alerts are a great way to keep your employees updated. Has a new security threat been discovered or an important plug-in released for the optimal functioning of a browser? Send an email to everyone spelling out clearly what the threat is and what they can do to mitigate it. Then, follow up to verify they took the necessary steps.

Transparency

Let your employees know who to contact in the event of any IT related challenges. This is important because someone troubleshooting on the internet for a solution to something as simple as a zipping up a file could end up downloading malware accidentally.

Considering the serious ramifications brought on by cybercrime attacks, it makes sense for organizations to strengthen their first line of defense against cybercriminals–their own employees.

Strengthening your cybersecurity policies

Reliable Networks on November 14, 2024

Strengthening your cybersecurity policies

Formulating strong IT policies and laying down the best practices for your staff to follow is one of the best ways to prevent your business from becoming a victim of cybercrime. In this blog, we explore the various areas your IT policy should ideally cover.

Passwords: Your IT policy should cover

  1. Rules regarding password setting
  2. Password best practices
  3. The implications of password sharing
  4. Corrective actions that will be taken in the event the password policy is not followed

Personal devices

  1. Rules regarding the usage of personal devices at work or for work purposes. Answer questions like
    1. Are all employees allowed to use personal devices for work or do you want to limit it to those handling lesser sensitive data, or to those at higher in the corporate hierarchy as you assume they will need to be available 24/7? Regardless, you should spell out the regulations that they must follow. For example, requiring a weekly or monthly check for malware and updates to anti-malware software, etc., If only certain kinds of devices, software or operating systems may be approved as they are presumed to be more secure, then that should be addressed in the policy

  2. Discuss best practices and educate your employees on the risks related to connecting to open internet connections (Free WiFi) such as the ones offered at malls or airports.

Cybersecurity measures

  1. Document the cybersecurity measures that you have in place for your business. This should include your digital measures such as the software you have deployed to keep malware out–like anti-virus tools, firewalls, etc., and also the physical measures such as CCTV systems, biometric access controls, etc.,
  2. Another example of a good practice is how you handle employee turnover. When someone quits your organization or has changed positions, how is the access issue addressed? Spell out the rules and regulations regarding the removal of a user from the network, changing passwords, limiting access, etc.,

Why do you need a top-down approach to IT security?

Reliable Networks on November 7, 2024

Why do you need a top-down approach to IT security?

For any organization, its employees are its biggest assets. But, what happens when your biggest assets turn out to be your greatest threats or liabilities? That is how cybercrime can change the game. In a recent study, it came to light that employee actions account for about 70% of the data breaches that happen. This blog focuses on the first step you need to take as an organization to better prepare your employees to identify and mitigate cyber threats–adopting a top-down approach to IT security.

Being a victim of cyber-attack can prove disastrous for your business as it has the following repercussions.

  • Affects your brand image negatively: Business disruption due to downtime or having your important business data including customer and vendor details stolen reflects poorly on your brand.
  • It can cause you to lose customers: Your customers may take their business elsewhere as they may not feel safe sharing their PII with you.
  • Can cost you quite a bit financially: Data breach makes you liable to follow certain disclosure requirements mandated by the law. These most likely require you to make announcements on popular media, which can prove expensive. Plus, you will also have to invest in positive PR to boost your brand value.
  • It makes you vulnerable to lawsuits: You could be sued by customers whose Personally Identifiable Information (PII) has been compromised or stolen.

The organizational mindset needs to change and acknowledge the fact that IT security is not ONLY your IT department, CTO or Managed Service Provider’s (MSP) responsibility. You need to truly believe that IT security is everyone’s business, and that includes everybody working in your company, from the C-level execs to the newly hired intern. Everybody needs to understand the gravity of a cyberattack and its impact. Only then will they take cybersecurity seriously.

6 Simple Steps to Enhance Your Email Security

Chris Provencher on November 5, 2024

Email is a fundamental communication tool for businesses and individuals alike. But it’s also a prime target for cybercriminals. Cyberattacks are increasing in sophistication. This means enhancing your email security has never been more critical.

Ninety-five percent of IT leaders say cyberattacks have become most sophisticated. Over half (51%) have already seen AI-powered attacks in their organization.

By taking proactive measures, you can protect your sensitive information as well as prevent unauthorized access and maintain communication integrity. Here are six simple steps to enhance your email security.

1. Use Strong, Unique Passwords

Passwords are the first line of defense for your email accounts. A weak password is like an open invitation for cybercriminals. To enhance your email security, use strong, unique passwords. Ones that are difficult to guess.

Create Complex Passwords

A strong password should include a mix of:

  • Letters (both uppercase and lowercase)
  • Numbers
  • Special characters

Avoid using common words or phrases. Also, avoid easily guessable information like your name or birthdate. A complex password makes it harder for attackers to gain access to your email account.

Use a Password Manager

Remembering several complex passwords can be challenging. A password manager can help you generate and store unique passwords for all accounts. With a password manager, you only need to remember one master password. This simplifies the process while enhancing security.

Avoid Reusing Passwords

Using the same password across many accounts increases your risk. If one account gets compromised, all accounts using the same password are vulnerable. Make sure each of your email accounts has a unique password. This prevents a single breach from spreading.

2. Enable Two-Factor Authentication (2FA)

Two-factor authentication (2FA) adds an extra layer of security to your email accounts. Even if someone gets hold of your password, they won’t be able to access your account. They would need the second factor of authentication to do that.

Choose a 2FA Method

Common 2FA methods include SMS codes, authenticator apps, and hardware tokens. SMS codes send a verification code to your phone. Authenticator apps generate time-sensitive codes on your device. Hardware tokens provide physical devices that generate a code. Choose the method that best suits your needs.

Set Up 2FA for All Accounts

Enable 2FA for all your email accounts. Most email providers offer this feature and setting it up usually takes just a few minutes. This simple step significantly improves your email security.

3. Be Cautious with Email Attachments and Links

Email attachments and links are common vectors for malware and phishing attacks. Clicking on a malicious link or attachment can give attackers access to your system. Exercise caution to protect your email security.

Verify the Sender

Before opening an attachment or clicking on a link, verify the sender’s identity. If you receive an unexpected email from someone you know, contact them. But do it through a different channel to confirm they sent it. For emails from unknown senders, exercise extra caution. Consider not engaging with the content.

Scan Attachments

Use antivirus software to scan email attachments before opening them. This helps detect and block any malicious content before it can harm your system. Many email providers also offer built-in scanning features. But having your antivirus software adds an extra layer of protection.

Avoid Clicking on Suspicious Links

Be wary of links that seem out of place or too good to be true. Hover over the link to see the URL before clicking. If the URL looks suspicious or unfamiliar, don’t click on it. Instead, navigate to the site directly through your browser.

4. Keep Your Email Software Updated

Software updates often include security patches that address vulnerabilities in your email client. Keep your email software updated. This ensures you have the latest protections against known threats.

Enable Automatic Updates

Most email clients and operating systems offer automatic updates. Enable this feature. It ensures your software stays up to date without requiring manual intervention. Automatic updates reduce the risk of missing critical security patches.

Regularly Check for Updates

Even with automatic updates enabled, it’s good to manually check for updates. This ensures you don’t miss any important security patches. It also helps keep your email client running smoothly and securely.

5. Use Encryption for Sensitive Emails

Encryption adds a layer of protection to your emails. It encodes the content, making it readable only by the intended recipient. This ensures that even intercepted email information remains secure.

Encrypt Emails Containing Sensitive Information

If you need to send sensitive information via email, use encryption. This protects the content. Many email providers offer built-in encryption options. For added security, consider using third-party encryption tools that offer end-to-end encryption.

Educate Recipients

If you’re sending encrypted emails, make sure the recipients know how to decrypt them. Provide clear instructions about how to access the encrypted content securely.

6. Watch Your Email Activity

Regularly monitoring your email activity can help you detect suspicious behavior early. By keeping an eye on your account, you can take swift action if something seems off.

Set Up Activity Alerts

Many email providers offer activity alerts. They notify you of unusual login attempts or changes to your account settings. Enable these alerts to stay informed about your account’s security status.

Regularly Review Account Activity

Review your email account activity on a regular basis. This includes login history and devices connected to your account. If you notice any unfamiliar activity, change your password immediately and investigate further.

Respond Quickly to Suspicious Activity

If you detect any suspicious activity in your email account, respond quickly. Change your passwords, review your security settings, and consider enabling extra security measures.

3 steps you can take to protect your data in the Cloud

Reliable Networks on October 31, 2024

3 steps you can take to protect your data in the Cloud

Moving to the Cloud offers tremendous benefits for SMBs that range from lower IT costs to any-time access to data and certainly more reliability in terms of uptime. But, data in the Cloud is also vulnerable to security threats just like the data stored on physical servers. This blog discusses 3 things you can do to protect your data in the Cloud

Secure access: The first step would be to secure access to your data in the Cloud. So, how do you go about it? Safeguard your login credentials-your User IDs and passwords-from prying eye. Set strong password policies that are practiced across the board and educate your employees about good password hygiene. Also, do you have employees using their own devices to access their work-related applications and documents? Do you have staff working from home? Then, you also need to formulate strong BYOD (Bring-your-own-device) policies, so these devices don’t end up as the entry point to cybercriminals.

Educate your employees: What’s the first thing that pops into your head when someone talks about cybercrime? You probably picture some unknown person, a tech-whiz sitting behind a computer in a dark room, trying to steal your data. But, surprising as it may seem, the first and probably the biggest threat to your data and IT security in general, comes from your employees! Malicious employees may do you harm on purpose by stealing or destroying your data, but oftentimes, employees unwittingly become accomplices to cybercrime. For example, forwarding an email with an attachment that contains a virus, or clicking on a phishing link unknowingly and entering sensitive information therein or compromising on security when they share passwords or connect to an unsecured or open WiFi at public places such as the mall or the airport with a view to “get things done”, but, without realizing how disastrous the implications of such actions can be.

Choosing the right Cloud service provider: If you are putting your data in the Cloud, you need to make sure that it is in safe hands. As such, it is your Cloud service provider’s responsibility to ensure your data is secure and, accessible, always. But, are they doing all that is needed to ensure this happens? It is very important to choose a trustworthy Cloud service provider because you are essentially handing over all your data to them. So, apart from strengthening your defenses, you need to check how well-prepared they are to avert the threats posed by cybercriminals.

Complete Cloud security is a blend of all these plus internal policies, best practices, and regulations related to IT security, and of course, the MSP you choose to be your Cloud security provider plays a key role in all this.

Is the Cloud really risk-free?

Reliable Networks on October 24, 2024

Is the Cloud really risk-free?

The Cloud presents plenty of benefits that make it a very attractive choice, especially for SMBs who don’t want to be burdened with higher in-house IT costs, putting your data in the Cloud is not risk-free. Just as storing data on physical servers has its security threats, the Cloud presents certain security concerns as well. These include

  • Data breach: A data breach is when your data is accessed by someone who is not authorized to do so.
  • Data loss: A data loss is a situation where your data in the Cloud is destroyed due to certain circumstances such as technological failure or neglect during any stage of data processing or storage.
  • Account hijacking: Like traditional servers, data in the Cloud could be stolen through account hijacking as well. In fact, Cloud account hijacking is predominantly deployed in cybercrimes that require entail identity thefts and wrongful impersonation
  • Service traffic hijacking: In a service traffic hijacking, your attacker first gains access to your credentials, uses it to understand the online activities that happen in your domain and then uses the information to mislead your users or domain visitors to malicious sites.
  • Insecure application program interfaces (APIs): Sometimes, Cloud APIs, when opened up to third parties, can be a huge security threat. If the API keys are not properly secured, it can serve as an entry point for cybercriminals and malicious elements.
  • Poor choice of Cloud storage providers: A security lapse from the Cloud storage provider’s end is a huge security concern for businesses. It is very important to choose a trusted and experienced Cloud service provider who knows what they are doing.

Apart from the above, there are some common threats that apply to both the Cloud and traditional data storage environments such as a DDoS attack, or a malware attack where your data in the Cloud becomes susceptible because it is being shared with others and at other places.

Some Cloud security mechanisms that SMBs can invest in to keep their data safe

Cloud firewalls: Much like the firewalls you deploy for your local IT network, Cloud firewalls work to prevent unauthorized Cloud network access.

Penetration testing: Penetration testing is a sort of a Cloud security check where IT experts try hacking into the Cloud network to figure out if there are any security lapses or vulnerabilities that could serve cybercriminals.

Obfuscation: In obfuscation, the data or program code is obscured on purpose such that the system delivers unclear code to anyone other than the original programmer, thus mitigating any malicious activity.

Tokenization: Tokenization is the process of replacing sensitive data with unique identification symbols that retain all the essential information about the data without compromising its security.1

Virtual Private Networks (VPN): Another, more commonly used mechanism is the VPN. VPN creates a safe passage for data over the Cloud through end-to-end encryption methodology.

Investing in a good Cloud security system is a must, but, in the end, you also need to remember that Cloud security is not only about antivirus software, firewalls, and other anti-malware tools. You need to pick the right MSP and work closely with them to implement a Cloud security solution that works for you.

Things to consider before switching to the Cloud

Reliable Networks on October 17, 2024

Things to consider before switching to the Cloud

More and more businesses are switching to the Cloud to store their data and rightly so. The Cloud offers numerous benefits over the traditional, physical on site server. For example,

  • Anytime, anywhere access to your data: Information in the Cloud can be accessed from anywhere using an internet connection, unlike in the case of traditional servers, where you need a physical connection to the servers
  • Significant cost savings: You cut hardware costs, because the Cloud follows a ‘pay-as-you-use’ approach to data storage
  • SaaS compatibility and support: The Cloud allows the use of Software-as-a-Service since the software can be hosted in the Cloud
  • Scalability: The Cloud lets you scale up and down as your business needs change
  • 24/7 monitoring, support, and greater access reliability: When your data is in the Cloud, the Cloud service provider is responsible for keeping it safe and ensuring it is securely accessible at all times. They monitor the Cloud’s performance and in the event of any performance issues, they provide immediate tech support to resolve the problem

Your big Cloud move: What to consider

If you are considering moving to the Cloud, you will find it helpful to sign-up with an MSP who is well-versed with the Cloud. They can advise you on the benefits and risks of the Cloud and also offer the Cloud solution that’s right for you. In any case, before you migrate to the Cloud, make sure you are dealing with a reputed Cloud service provider who has strong data security measures in place. You can even explicitly ask them what security mechanisms they have invested in to manage data access and security.

Yes, moving to the Cloud has it benefits, but it also has its challenges including security risks. Learn more in our next blog, “Is the Cloud really risk-free?”
