What does a CISSP do?

What does a CISSP do?

A CISSP is a professional certification. To attain CISSP, a professional must pass a six-hour, 250-question test and must have five years of professional experience doing work related to computer security. But after attaining the certification, what does a CISSP do?

An easy question on the test would involve what you have to be concerned about when running network cable through an HVAC duct. A medium-difficulty question might ask whether the CDMA or GSM standard for cell phones is more secure, and why. A hard question or series of questions would involve reading several pages of executive summary about a data breach and making recommendations to prevent it from happening again.

Difference between antivirus and antimalware

Difference between antivirus and antimalware

The difference between antivirus and antimalware is largely academic, but understanding it can help you understand what protection you’re getting when you buy off-the-shelf security software.

How hard is Security+?

Many jobs require Security+, and even if a job doesn’t require it, having Security+ can help you break into your first security job. So how hard is Security+?

When you understand motive, then the relationship can move from following orders to something more collaborative, which is always a good thing.

Running it gave me an error message. Here’s what to do when Windows says the update is already installed on this system and refuses to let you do anything but click OK.

Because hey, from a security analyst’s point of view, this is anything but OK. I get questions about patches in a partially deployed state all the time, so I figured I’d write about it.

Finding and blocking an abusive host from your Apache log

Finding and blocking an abusive host from your Apache log

My web site slowed to a crawl last night, my CPU usage soared to 100%, and my built-in security measures weren’t helping. I ended up having to do some old-school Linux sysadmin work to stop them.

I haven’t been an everyday sysadmin since 2009. But every once in a while I can still come off the bench and do this stuff.

Watering hole attack prevention

Watering hole attack prevention

A watering hole attack is an indirect attack on a victim. Rather than directly attacking the victim’s network, the attacker attacks a web site that the victim’s employees are likely to visit. Then the attacker attacks the victim’s network, via its own workstations, from that web site. A former colleague asked me how you protect against watering hole attacks, and I thought this was a good exercise. So here are some strategies for watering hole attack prevention.
