As a security admin, you’re always committed to the security and privacy of the users in your network. However, despite your commitment, the fact remains that without comprehensive monitoring in all the right areas, your network will still be prone to targeted attacks.
The Opera Security Breach
The recent incident at The Opera Security group stands as a perfect example of a breach due to inadequate network monitoring. Initially it appeared that the attack was uncovered and no user data was compromised. However, upon closer inspection the security team found that this was no ordinary attack. The attackers had not tried to steal intellectual property, instead they wanted to use Opera’s auto-update mechanism to propagate a piece of malware normally associated with Trojans. As a result, the users received the malware as part of the browser update.
How to stay guarded?
You need to effectively identify and respond to threats in real-time rather than being reactive. The Opera Breach incident reiterates the importance of continuously monitoring the activities on your Web server, firewalls and endpoints. It’s advisable to use SIEM security software that can help you identify anomalies and deviations in policy definitions, baseline your IT environment for vulnerabilities, and shield your IT environment from vulnerabilities. SIEM security software also helps you to analyze and correlate activities across the various components of IT.
Further, it makes utmost sense if the SIEM software uses active responses to respond to critical events and shuts down threats immediately. For example, automatically blocking an IP address upon identifying policy deviations.
Stay updated but cautiously!!
Although the Opera security update incident led to a breach, it doesn't mean you should be skeptical about every update that you get from vendors. The more you fail to keep up with security updates from your software vendors, the more you’re prone to vulnerability. Unpatched applications are prone to become entry points for security attacks, thus making patch management one of the most critical processes in vulnerability management.
SolarWinds® Patch Manager to the rescue!!
SolarWinds Patch Manager is an easy to use tool that helps you report, deploy, and manage Opera patches. It simplifies and centralizes the patch management process by:
Preparing patch deployment packages for Opera with the latest updates and bug fixes
Testing the Opera patches before actual deployment and analyzing the post implementation results, thereby helping bulk deployment
Creating advanced before-and-after package deployment scenarios to ensure that complicated patches are deployed without complicated scripting
Ensuring compliance through automated patching with the help of built-in reports and custom reports that allow you to check whether the patch was successful or failed during deployment
In order to achieve comprehensive network monitoring, it’s best to have a hawk-eye on the events in your network and update your security software regularly to minimize vulnerabilities.
