Cryptographic Hashes: Verifying the Integrity of Your File System Baseline

We have discussed the importance of establishing a baseline for data flow across your network and the criticality of identifying abnormal activity before it wreaks havoc on your business systems. The National Institute of Standards and Technology (NIST) recommends IT cybersecurity teams use cryptographic hashes to detect unauthorized changes to software, firmware and information stored on your network.

Carefully Testing your Antivirus Software on the Web

The roles of antivirus (AV) software and intrusion detection systems (IDS) are similar and straightforward - to detect malicious activity targeting your systems. NIST Cybersecurity Framework recommends that you test detection processes as a key function of security (akin to testing smoke alarms and fire extinguishers for proper functionality before they are needed). Here we discuss testing your antivirus and IDS to be sure they are functioning properly and protecting your networks.

Detecting Malware Using a Centralized Antivirus Management System

Previously we touched on the basics of what to do when your antivirus (AV) software indicates that it has found malicious code in the form of a virus, worm or trojan. This foundational knowledge should be seen as a starting point, especially if you own or support a small to medium sized business (SMB). As your business grows to a more complex network setup, you may face additional cyber threats in both quantity and their ability to do permanent damage to your information and your bottom line.

Don’t Ignore Antivirus Software Warnings

When it comes to computer viruses, just like the common cold, prevention is always the best cure. Stay vigilant and minimize your company’s risk of infection by understanding how malicious code functions, the most common ways it spreads between systems and how you can detect and stop it.
