Security information and event management, or “SIEM,” is a tool that assimilates all of your log data to give you an all-encompassing overview of the activity on your network. SIEM tools watch over your network and help you stop trouble in its tracks. Whether your organization has 200 or 20,000 employees, SIEM software can be a vital part of any company’s cybersecurity posture.
Your first day at a new internship can seem intimidating. For most of us, it’s our first look into the professional world. Although you learn important concepts in school, the experience you gain in a professional setting is much more valuable; especially in the cybersecurity industry. 60 days into my cybersecurity internship at ProCircular, the team has taught me much more than I’ve learned on my own. Before my time on ProCircular’s red team, I was only able to learn about cybersecurity concepts through internet resources, such as TryHackMe, and different books I found online. The opportunity to be an intern has enabled me to grow my skills and knowledge through hands-on experience with real companies around the country. Practicing vulnerability assessments and social engineering in an environment where it is legal is, by far, a great improvement compared to assessing my own home network. It’s exciting to see the different services that real companies have and the different ways those real companies try to secure them. It’s a much more engaging and volatile environment than what you get in online learning.
Incident Response is a series of investigative and remedial steps that a company takes in the event of a breach or other security incident. These restoration efforts can include backtracking through log data, isolating affected machines, and even negotiating with cyberterrorists!
In 1974, the great Mohammed Ali said of his opponent, George Foreman, “His hands can’t hit what his eyes can’t see.” The same principle rings true in the cybersecurity world; we can't stop an attack until we know it is happening. That is why SIEM experts, like ProCircular’s Josh Resch, dedicate themselves to monitoring our clients’ networks for suspicious activity. Although each SIEM product works a little differently, they are all designed to help identify and track early signs of malicious activity on your network. A well-maintained SIEM can drastically reduce recovery time from a security incident by showing exactly where the attacker has been.
The best approach to security is a proactive one, but nobody is perfect. What happens when a determined attacker finds their way into your network? How do you know where they have been, what they have seen, when they got in, and how they gained access? How do you prioritize remediation and confirm that the bad guys are out of your network? Incident responders, like ProCircular's Aaron Heikkila, are at the ready to swoop down and stop the attackers in their tracks!
