The recent Log4J vulnerability brought increased attention on 0 day attacks, but it’s a question that never really goes away. How common are zero day attacks?
Zero day attacks are less common than they seem because attackers don’t understand them as well as less exotic attacks. Managing those less exotic vulnerabilities is a real challenge for many organizations, but it’s something they must get a handle on to defend themselves effectively.
If you work in IT or security, you are pretty much expected to know what a user story is. That can be a problem if your background is not in software development, or if your education or background predates the agile software development model. So what is a user story and how do you write one?
User stories are similar to milestones in project management. That was how it was first explained to me. But you don’t write a user story quite the same way that you would write a milestone in project management. The other thing is mixing the two can lead to miscommunication. I was once involved in a meeting where a manager insisted on using user stories, because he had been a software developer, but this wasn’t a project involving software development. So nobody else knew what he was talking about.
User stories are a product management or software development tool. They aren’t something everyone knows.
Sometimes, if you get a new device, or if you connect to a network you’ve never connected to, you can receive a message that says your Wi-Fi is not secure. Why does my wifi say not secure? Here’s why, and also why you shouldn’t ignore that message.
That message got your attention, didn’t it? It’s designed to get your attention. And it’s really easy to dismiss it as being alarmist. People have a tendency to either greatly overestimate or underestimate how much interest someone might have in attacking them. Especially if I tell you that the security that you’re getting a warning about has much more to do with privacy than it does with viruses. That message does not mean that this network is any more or less likely to infect you with a viruses.
But you need to do something about it when you see this message. First let me tell you why, then I will tell you what you need to do.
Over the weekend of Nov 13, 2021, the FBI acknowledged unauthorized emails coming from a legitimate FBI email address to about 100,000 organizations warning them about ransomware. It appears to be the work of a self-styled white hat hacker, or security researcher.
I am a security professional. I am going to remind everyone that these are not the opinion of my current or any former employer. I have strong opinions on the, and those opinions are incredibly unpopular among security professionals. They may or may not agree with me privately, but agreeing with me publicly is not a great idea.
It is important to know how to distinguish between a private vs public IP address. IT professionals and security professionals frequently have to work with them, and it is a very common job interview question, and certification question. Here are the ranges of private IP addresses, and why we need them.
I hear the argument all the time that if you aren’t doing anything wrong, you don’t have to worry about privacy. So is data privacy important? I’ll tell you why it is.
There was a very vocal element of society that was very anti-data privacy until 2021. Once the COVID vaccine was released, suddenly they became very concerned about their privacy. I hope that element of society learned some empathy from this. How they felt about their privacy is how the rest of us feel when it comes to large corporations tracking our every move.
I definitely have mixed feelings about LinkedIn. It’s helped me get several jobs, but it can also have the same pitfalls of any social network. Plus some that are unique to LinkedIn. If Linkedin is annoying you, here are some things I did to make LinkedIn less annoying and more helpful.
What is ASM in security? ASM stands for attack surface management. It solves a real security problem. But it may not be the security problem that you think it solves, and it also doesn’t solve it as completely as it sounds like it may. Let’s talk about what ASM does and whether you might want it.
In Australia, they have a national day called R U Ok. And one of my Australian coworkers used that as an opportunity to reach out to the rest of the company. We all thanked him. Mental health is a problem in the field of computer security, and IT as a whole, and we rarely talk about it. It’s time that we start. Let’s take the taboo out of mental health and infosec.
I had a discussion with somebody this week about vulnerabilities that don’t have CVEs. I learned from this conversation that there are a lot of misconceptions about those. So let’s talk about vulnerabilities without CVEs, and what to do about them.
