One of my favorite Christmas carols is the 12 Days of Christmas. Back in the 90's, a satire of the song came out in the form of the 12 Pains of Christmas, which had me rolling on the floor in laughter, and still does. Now that I am in information security, I decided it is time for a new satire, maybe this will start a new tradition, and so I am presenting, the 12 Pains of Infosec.

The first thing in infosec that's such a pain to me is your password policy

The second thing in infosec that's such a pain to me is default credentials, and your password policy

The third thing in infosec that's such a pain to me is falling for phishing, default credentials, and your password policy

The fourth thing in infosec that's such a pain to me is patch management, falling for phishing, default credentials, and your password policy

The fifth thing in infosec that's such a pain to me is Windows XP, patch management, falling for phishing, default credentials, and your password policy

The sixth thing in infosec that's such a pain to me is Lack of input filtering, Windows XP, patch management, falling for phishing, default credentials, and your password policy

The seventh thing in infosec that's such a pain to me is no monitoring, lack of input filtering, Windows XP, patch management, falling for phishing, default credentials, and your password policy

The eighth thing in infosec that's such a pain to me is users as local admins, no monitoring, Lack of input filtering, Windows XP, patch management, falling for phishing, default credentials, and your password policy

The ninth thing in infosec that's such a pain to me is lack of management support, users as local admins, no monitoring, lack of input filtering, Windows XP, patch management, falling for phishing, default credentials, and your password policy

The tenth thing in infosec that's such a pain to me is testing for compliance, lack of management support, users as local admins, no monitoring, lack of input filtering, Windows XP, patch management, falling for phishing, default credentials, and your password policy

The eleventh thing in infosec that's such a pain to me is no asset management, testing for compliance, lack of management support, users as local admins, no monitoring, lack of input filtering, Windows XP, patch management, falling for phishing, default credentials, and your password policy

The twelfth thing in infosec that's such a pain to me is trust in antivirus, no asset management, testing for compliance, lack of management support, users as local admins, no monitoring, Lack of input filtering, Windows XP, patch management, falling for phishing, default credentials, and your password policy

The first thing in infosec that's such a pain to me is your password policy

When I go into organizations for penetration tests, one of the easiest ways to get in is through password guessing. Most organizations use a password policy of 8 characters, complexity turned on, and change every 90 days. So, what do the users do? They come up with a simple to remember password that will never repeat. Yes, I am talking about the infamous Winter16 or variations of season and year. If they aren't using that password, then chances are it is something just as simple. Instead, set a longer password requirement (12 characters or more) and blacklist common words, such as password, seasons, months, and company name.

The second thing in infosec that's such a pain to me is default credentials

The next most common finding I see is the failure to change default credentials. It is such a simple mistake, but one that can cost your organization a ton! This doesn't just go for web apps like JBOSS and Tomcat, but also for embedded devices. Printers and other embedded devices are a great target since the default credentials aren't usually changed. They often hold credentials to other systems to help gain access or simply can be used as a pivot point to attack other systems.

The third thing in infosec that's such a pain to me is falling for phishing

Malicious actors go for the weakest link. Often this is the users. Sending a carefully crafted phishing email is almost 100% successful. In fact, even many security professionals fall victim to phishing emails. So, what can we do about it? Well, we must train our employees regularly to spot phishing attempts as well as encourage and reward them for alerting security on phishing attempts. Once reported, add the malicious URL to your blacklist, and redirect to a phishing education page. And for goodness sake, Security Department, please disable the links and remove any tags in the email before forwarding off as "education".

The fourth thing in infosec that's such a pain to me is patch management

There are so many systems out there. It can be hard to patch them all, but having a good patch management process is essential. Ensuring our systems are up to date with the latest patches will help protect those systems from known attacks. It is not just operating system patches that need to be applied, also for any software you have installed.

The fifth thing in infosec that's such a pain to me is Windows XP

Oh Windows XP, how I love and hate thee. Even though Windows XP support went the way of the dodo back in 2014, over 2.5 years later I still see it being used in corporate environments. While I called out Windows XP, it is not uncommon to see Windows 2000, Windows Server 2003, and other unsupported operating system software. While some of the issues with these operating systems have been mitigated, such as MS08_067, many places have not applied the patches or taken the mitigation tactics. That is not to mention what unknown security vulnerabilities that exist and will never be patched. Your best bet is to upgrade to a supported operating system. If you cannot for some reason (required software will not run on newer operating systems), segregate the network to prevent access to the unsupported systems.

The sixth thing in infosec that's such a pain to me is lack of input filtering

We all know and love the OWASP Top 10. Three of the top 10 is included in this pain. Cross-Site Scripting (XSS), SQL Injection (SQLi), HTML Injection, Command Injection, and HTML Redirects are all vulnerabilities that can be solved fully, or at least partially in the case with XSS, with input filtering. Web applications that perform input filtering will remove bad characters, allow only good characters, and perform the input filtering not at the client-side, but at the server-side. Then using output encoding/filtering, XSS is remediated as well.

The seventh thing in infosec that's such a pain to me is no monitoring

In 1974, Muhammad Ali said “His hands can't hit what his eyes can't see” referring to his upcoming fight with George Foreman. This quote bodes true in Infosec as well. You cannot defend what you cannot see. If you are not performing monitoring in your network, and centralized monitoring so you can collaborate the logs, you will miss attacks. As Dr. Eric Cole says “Prevention is ideal, but detection is critical.” This is also critical to REVIEW the logs, meaning you will need good people that know what they are looking for, not just good monitoring software.

The eighth thing in infosec that's such a pain to me is users as local admins

Though for years we have been suggesting to segregate user privileges, yet almost every penetration test I perform I find this to be an issue. Limiting use of accounts to only what is needed to do their job is very hard, but essential to secure your environment. This means not giving local administrator privileges to all users but also using separate accounts for managing the domain, limiting the number of privileged accounts, and monitoring the use of these accounts and group memberships.

The ninth thing in infosec that's such a pain to me is lack of management support

How often do I run into people who want to make a change or changes in their network, yet they do not get the support needed from upper management? A LOT! Sometimes an eye-opening penetration test works wonders.

The tenth thing in infosec that's such a pain to me is testing for compliance

I get it, certain industries require specific guidelines to show adequate security is in place, but when you test only for compliance sake, you are doing a disservice to your organization. When you attempt to limit the scope of the testing or firewall off the systems during the test, you are pulling a blinder over your eyes, and cannot hope to secure your data. Instead, use the need for testing to meet compliance a way to get more management support and enact real change in the organization.

The eleventh thing in infosec that's such a pain to me is no asset management

You can't protect what you don't know about. In this regard, employ an asset management system. Know what devices you have and where they are located. Know what software you have, and what patch levels they are at. I can't tell you how many times I have exploited a system and my customer says “What is that? I don't think that is ours”, only to find out that it was their system, they just didn't have good asset management in place.

The twelfth thing in infosec that's such a pain to me is trust in antivirus

A few years ago, I read that antivirus software was only about 30% effective, leading to headlines about the death of antivirus, yet it still is around. Does that mean it is effective in stopping infections on your computer? No. I am often asked “What is the best antivirus I should get for my computer?” My answer is usually to grab a free antivirus like Microsoft Security Essentials, but be careful where you surf on the internet and what you click on. Antivirus will catch the known threats, so I believe it still has some merit, especially on home computers for relatives who do not know better, but the best protection is being careful. Turn on “click to play” for Flash and Java (if you can't remove Java). Be careful what you click on. Turn on an ad blocker. There is no single “silver bullet” in security that is going to save you. It is a layering of technologies and awareness that will.

I hope you enjoyed the song, and who knows, maybe someone will record a video singing it! (not me!) Whatever holiday you celebrate this season, have a great one. Here's to a more secure 2017 so I don't have to write a new song next year. Maybe “I'm dreaming of a secure IoT” would be appropriate.
