I had an update on my system in a partially installed state. Our vulnerability scanner determined one file, MSO.dll, was still out of date. It recommended a patch to apply. 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.
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.
One of my clients asked me to explain superseded patches and how they relate to vulnerability management and patch management. This is a common question about a common complaint. Knowing the meaning of superseded patches and how to handle them is absolutely critical for running a successful security program.
As a vulnerability management professional, I talk about vulnerability scanning best practices a lot. There’s a lot more to vulnerability management than just scanning, but if you don’t get scanning right, the rest of the program suffers.
I’m going to talk about a lot of technical controls here, but don’t forget the nontechnical side. People and processes have to support all technology.
If you’re standing at a checkout and the chip won’t work on your credit card, don’t give up right away. Here’s what to do when you swipe but can’t complete your purchase because your chip doesn’t work.
Chips are a new security feature, but it’s hard to appreciate them when a broken chip keeps you from completing your purchase. It happened to a longtime friend, and another friend of his provided a solution. I had to share it, because I know it will happen to others.
As a security professional, I talk to a lot of people about common security attacks and countermeasures. I’m not always certain the people I’m talking to know what these things mean. I am almost certain they aren’t willing to ask.
I know it’s more complicated than it was when I took my Security+ exam a decade ago. The stakes are much higher now. The attacks I had to identify caused inconvenience, but someone conducting a successful smurf attack on your printer won’t get you in the headlines. Today’s attacks will.
Someone asked me the other day how does MAC address filtering help to secure a wireless network? If you’re in a position where it would help, I argue there are other things you need to do. But I’ll explain how it works, then what I’d rather you do instead.
USB flash drives are pretty much a necessity these days. They’re far more convenient for moving files around than optical discs, and they make good backup devices. But not all USB flash drives are created equal. Here’s what to look for in a USB flash drive.
Here’s a tip: I don’t just use USB flash drives for transporting data and backups. I like to keep a modest-sized USB flash drive plugged into my router, turning it into a small NAS. It gives me a convenient, reliable place to back up data from any of my computers.
