Malware is short for “malicious software,” which is an overarching phrase referring to malicious code designed to cause problems. Malware often injects code into applications to execute viruses or trojans. One of the most common types of malware is a variant called ransomware, which you’ve probably heard of thanks to a number of high-profile infections. When a machine is infected with ransomware, it encrypts the files on the device until the ransom is paid to the hacker. Aside from this rather dangerous strain, other types of malware can have far-reaching and varied effects.
Like malware, a rootkit is at home on a system. Unlike some types of malware, however, a rootkit is designed to allow a hacker to gain control of a system while remaining undetected for extended periods of time. Rootkits are dangerous thanks to their ability to avoid detection by software that’s supposed to find them, like firewalls and antivirus solutions.
Trojans are malicious entities that allow hackers to access a system by misleading the user. Trojans are backdoors that can allow hackers access to a system at a later date, and they are often installed alongside other malware to distract the user from taking preventive action. The trojan can be used for a number of purposes, from data destruction to surveillance or espionage.
The Solution: Preventative Security Measures
Since so many threats are blocked by preventative security measures, it would be foolish not to implement them. There are several ways you can keep threats out of your system, including:
- Firewall: Firewalls act as a bouncer for your network, keeping threats from entering or leaving your infrastructure. They work best when combined with other preventative measures, like antivirus, content filters, and spam blockers.
- Antivirus: Antivirus solutions detect and eliminate threats that have made it past your firewall solution. Antivirus offers prompt threat detection, which is important since malware that’s left unchecked could cause untold troubles.
- Spam blocker: Threats often arrive in your email inbox as spam, and the unknowing employee could accidentally click a malicious link or reveal important credentials. A spam blocker eliminates the vast majority of spam from even hitting your inbox.
- Content filter: A content filter is helpful for keeping your employees from accessing sites known to host malware, as well as inappropriate or time-wasting sites, like social media.
A Unified Threat Management (UTM) solution is a great way to take advantage of all of the above solutions. It’s widely considered to be the most comprehensive and useful preventative measure available to SMBs. If you want to learn more about UTMs, be sure to give Aspire a call at (469) 7-ASPIRE.
