As an entrepreneur,it is important that you take precautions to keep your systems safe from outside threats. “Zero-day” exploits are becoming increasingly common, and these vulnerabilities involve a rapid attack that takes place before the vendor or security community even knows that it exists. This lets hackers take advantage of the company’s lack of awareness, allowing them to wreak maximum havoc in a short period of time. Fortunately, there are ways that you can protect your company.
Invest in real time protection
While it is important to take preventive efforts to try and ward off zero-day threats before they become a problem, you’ll also need to have a plan in place to handle a problem if it does arise. This should involve real-time protection like intrusion-prevention systems (IPS). An IPS should offer comprehensive protection, but there are certain capabilities that you will want to look for when choosing a system:
- Application integrity checking
- Application protocol RFC validation
- Content validation
- Forensics capability
- Network-level protection
An intrusion prevention detection system can help to protect your company from vulnerability, as their rules and protocols can work to prevent a zero-day attack.
Take preventive efforts
While it may be impossible to completely protect your company against zero-day exploits, taking preventive efforts to try and keep your business safe is a necessity. Preventive security practices include installing a good firewall policy and keeping it up to date. These policies should match the application and business needs, blocking file attachments that can be harmful and ensuring that all systems are patched against vulnerabilities. Systems that regularly conduct vulnerability scans are also a good way to measure how effective your preventive procedures are.
Plan Your Incident Response Strategy
Even if you take precautions in order to protect your company from a zero-day threat, you can still get infected. A well-planned incident response strategy is crucial if the unthinkable should happen and your system should become compromised. The best incident response strategy will contain well-defined procedures and rules, including prioritization of activities that are mission-critical. These activities will be crucial to minimize business damage.
Minimize the Spread
If your system is compromised by a zero-day exploit, you’ll need to take steps to prevent the spread of the problem. This can be completed by limiting your connections to only those that are necessary for your business needs. This will help to control the spread of the exploit within your organization after your company has experienced the initial infection.
So, after you have been hacked by a zero-day exploit, what exactly should you do? While your first instinct might be to shut down all the computers on your network, this is a bad idea. A lot of hackers can breach your system using memory-only malware, which installs onto your RAM, but not the hard drive, since this type of exploit doesn’t leave a lasting data footprint, it can bad difficult to track. Shutting down your computer network could erase the evidence that would prove helpful in tracking the source of the exploit.
Don’t leave your company’s systems vulnerable to zero-day exploits. By taking these steps, you can avoid damage due to these newly created vulnerabilities.
