It is possible to prevent zero-day attacks? Protecting your business against the latest IT threats should always be a top priority. Updating your antivirus and patching your operating system is a great way to start to protect against emerging threats and zero days. What happens, however, when a threat appears at your door before security firms have had a chance to catch it?
Zero Day Attacks
A zero-day attack refers to a cyber-attack exploiting a vulnerability in software, hardware, or firmware that is unknown to those responsible for patching or fixing the flaw.
The term “Zero Day” implies that developers have zero days to address the vulnerability to prevent its exploitation. These attacks are particularly dangerous as they can go undetected until they are leveraged, offering the threat actor unfettered access to potentially sensitive data or systems.
What is a Zero-Day Attack vs. Zero-Day Vulnerability?
A security threat that exploits a previously undiscovered software vulnerability somewhere in the same computer system is known as a zero-day threat. The name “zero-day” is designed to imply how long since the vulnerability was discovered. The term also indicates that system developers have had zero days to fix it.
Zero-day attacks are vulnerabilities so new that security researchers and firms have never seen them before and have had zero days to fix them. Luckily, it is possible to lessen the chances of it impacting you or your business.
A zero-day attack is an attack that exploits a security vulnerability that has not been publicly disclosed. This means that the attacker knows about the vulnerability before the vendor or the general public does, giving them a window of opportunity to exploit it before a fix is released.
A zero-day vulnerability is a security hole in a computer program that the vendor or developer is not yet aware of. This means that there is no patch or fixes available, and the vulnerability can be exploited by attackers before it is fixed.
Zero Day Protection
Zero-day protection is a security measure that is designed to protect against zero-day vulnerabilities and one-day attacks. This can include things like keeping your software up to date, using security software, and avoiding clickbait and phishing attacks.
A zero-day virus is a type of malware that takes advantage of a zero-day vulnerability. This means that the attacker has found a way to exploit the security hole before the vendor or developer is aware of it. The zero-day malware virus can then spread and cause damage to the system.
A newly discovered attack might be packaged into a computer virus or worm. This will allow it to spread far and wide while inflicting the maximum amount of damage possible. When spread successfully, a new exploit has the potential to reach hundreds of thousands of computers before an operating system or anti-virus update can even be issued.
There are several ways we can protect your business or lessen the damage from a zero-day attack.
#1. Preventative security
The number one way to mitigate the damage from any attack on your system is to prevent it from happening in the first place. Maintaining a good firewall and up-to-date antivirus is the best step you can take to ensure the security of your system.
A firewall, monitoring incoming traffic in and out of your network, reduces the threat intelligence unauthorized entry over the network. Even without knowing the exact nature of the attack, suspicious activity traveling in and out of the system can be stopped.
The same is true of modern Antivirus. Even when it can detect malware but not identify the specific zero-day threat from its virus database; it can often identify malicious intent from learned behavior in the system.

#2. A Locked Down Network
Should a zero-day threat make it into your network, our next goal should be to limit its effects. By restricting user access to only essential files and systems we can limit the damage done to the smallest number of systems. A good security policy dictates that each account should only have full access to the systems needed to complete the user’s job. For example, users from the accounts department shouldn’t have access to sales department databases.
In this way, the damage of a single compromised account is limited to only the network area it operates in. Such limited impact should be easy to command and control the server and can be reversed with regular backups.
#3. Good Data backup
Whether your entire network has been exploited or only a small area has been affected; good data backups are your protection against major lasting damage. Having a good backup means having the procedures in place to both create regular backup copies and make sure they can be restored at a later date.
Reliable and well-tested backups are worth their weight in gold. Knowing your data is safe and your system can be recovered is peace of mind against even the most highly destructive of zero-day exploits and one-day attacks.
#4. Intrusion Protection
While the precise methods of a zero-day exploit can’t be known in advance, a network intrusion protection system (NIPS) can monitor the firms’ network for unusual activity.
The advantage of NIPS over a traditional antivirus-only system is it does not rely on checking software against a known database of threats. This means it does not make software vendors need updates or patches to learn about the latest attacks. NIPS works by monitoring the day-to-day patterns of network activity across the network.
When traffic or events far out of the ordinary are detected action can be taken to alert system administrators and lock down the firewall. Devices such as USB drives and mobile devices can all introduce threats to the network. They can often make it past the firewall because they are physically introduced to the system.
NIPS protects against threats introduced to the network from both external and internal sources.
When antivirus isn’t enough, consider MDR – Managed Detection and Remediation. Learn more here: https://cybriant.com/mdr/
#5. Full Cover Protection
Used in combination with these techniques, security teams can prevent, protect against zero days, and mitigate against the kinds of threats that even the top security firms haven’t patched yet. We think it’s important to keep your firm secure whatever it might come up against in the future. And, having security experts on hand 24/7 is a nice bonus.
