Preparing for Zero Day Attacks

Dealing with unpredictable zero day vulnerabilities is one of the greatest challenges faced by today’s security teams. How can you minimize risk across your supply chain?

SolarWinds, Colonial Pipeline, Zoom, and Log4j have become synonymous with infamous cybersecurity incidents. Don’t let every new zero-day vulnerability be a “wake-up call”.
Stay awake. Be proactive.


 
 

FAQ about Zero Day Vulnerabilities

What is a zero day vulnerability?

A zero day (also referred to as 0-day) is a software vulnerability either unknown to its developer, or known and without a patch to fix it. The name comes from the fact that the vendor has practically “zero days” to fix it as no patch exists yet.
Until the vulnerability is mitigated, attackers can exploit it to affect programs, data, additional computers, or a network. An exploit that uses a zero-day vulnerability is called a zero-day exploit, or zero-day attack.

How common are zero day events?

Very. Software is written by humans, and humans are fallible. Some code structures are harder than others to analyze in search for weak spots, and even automated checking tools sometimes have trouble finding them.
When either through research, accidental, or malicious misuse, one of those weak spots in the code is discovered, it’s called a “vulnerability” in the software. Vulnerabilities have been around as long as software has. It’s just a matter of who finds them first and what they do about them.

Can you prevent zero day attacks?

As organizations embrace digital transformation and engage with more third party vendors and software providers, it’s becoming increasingly hard to prevent vulnerabilities completely.
The best thing you can do is be proactive and implement a layered defense strategy, both internally and across your supply chain. You never know when a problem like this will occur, but if you don’t rely entirely on a single security measure or type of technology, you will be more likely to weather the inevitable storm without serious harm.
This includes applying patches and updates as soon as they become available after a zero day is reported, as well as reinforcing security standards as part of your vendor risk assessments.

How is third party risk management (TPRM) related to zero day vulnerabilities?

Zero day vulnerabilities could not only affect your organization directly, but also through one of your third party vendors. Which is why vendor risk assessments and continuous monitoring of their security performance are the pillars of a third party risk management program.
As part of your due diligence and continuous reassessment processes, you need to make sure that your vendors are enforcing standards that keep your business safe. Should a zero day vulnerability appear, you can ask your vendors if they’re vulnerable, how are they planning to respond, or request additional assurances —all through a standardized third party risk management process.

What to do if your organization was affected by a zero day

Follow these steps for vulnerability remediation

1.

Patch your systems


Vendors and makers usually act fast to issue a patch once the zero-day vulnerability is discovered. Install it as soon as it becomes available.

2.

Assess risk exposure


Identify vulnerable third party vendors in your supply chain and check if your own organization is vulnerable.

3.

Update your requirements


Ask your third parties for additional security requirements and assurances, and add them to your upcoming vendor contracts if needed.

4.

Show your strength


If you are a vendor to other organizations, share an update of your security posture to let them know you already took the necessary steps.

5.

Track, report, and conclude

Vulnerability management includes identifying, analyzing, remediating, and reporting phases; make sure everything is documented.
