You can buy all the security gear in the world, but if you don’t know where your weaknesses are, you’re just guessing. That’s where security assessments come in. These are a way to test your defenses and find vulnerabilities before a bad guy does.
There are a few different types of assessments, and each one has a different purpose.
The Different Types of Security Assessments
- Vulnerability Scans: This is an automated scan that looks for known vulnerabilities in your systems. It’s like using a metal detector to find a bunch of loose change on the beach. It’s fast, it’s easy, and it can find a lot of common problems, like unpatched software or misconfigured settings. It’s a great starting point, but it won’t find every problem.
- Penetration Testing: This is a more hands-on approach. A professional ethical hacker (a “pen tester”) tries to break into your network just like a real attacker would. They’ll try to exploit vulnerabilities, find weaknesses, and see how far they can get. This is the big one. It’s a real-world test of your security.
- Security Audits: A security audit is a formal review of your security policies and controls. It’s a check to make sure you’re following best practices and complying with any regulations. It’s more of a policy check than a technical test.
- Code Reviews: If you’re developing your own software, a code review is a must. A professional will manually or automatically check your application code for vulnerabilities. This helps find security flaws before the application even goes live.
The Three Types of Pen Tests
A pen test can be done in one of three ways, depending on how much information you give the tester:
- Black Box Test: The tester is given no information about your network. They have to start from scratch, just like a real-world attacker. This is the most realistic test.
- White Box Test: The tester is given full knowledge of your network, including network diagrams, source code, and user credentials. This is a very thorough test that can find a lot of deep-seated vulnerabilities.
- Gray Box Test: This is a mix of both. The tester is given some information, like a user account on your network, but not full access. This is a good way to test for insider threats.
Security assessments are a critical part of a proactive security program. You can’t just set up your defenses and hope for the best. You have to constantly test them to make sure they’re working.
