The war against malware continues… and will continue. As better methods to block attacks, detect malicious activity and thwart infections are developed, so will malware evolve. Cyber criminals target endpoints as it offers plenty of avenues for infiltration. Endpoints are considered to be the weakest point in terms of security in an enterprise IT system. Enterprises must ensure robust endpoint protection, and the best way would be through cloud security.
There are different types of malware such as viruses, worms, Trojans, spyware, rootkits, backdoors, key loggers, ransomware, and Browser Hijackers. Each type of malware serves a different purpose, and some malware are a combination of multiple types. A ransomware could be a combination of a worm, a Trojan, and a backdoor. Further, cyber criminals identify vulnerabilities in operating systems, applications and exploit them for attacks. Phishing and spear-phishing are other modes of attacks that trick users into opening malicious attachments or click on malicious links.
Typical antivirus security solutions are installed on the local server and endpoints. The malware definition database is stored locally and this list is periodically updated. The developers of the antivirus solution keep updating their malware database, and this data gets updated automatically or manually. There is, however, a certain time delay between the time that the AV company updates its database and the time the local database gets updated. This period is very critical, as zero-day malware can attack and infect the systems.
In order to overcome this vulnerability, and with the advent of faster internet, cloud-based security has been adopted. Small, medium and large enterprises must adopt cloud security for better and faster response to zero-day attacks.
As a basic practice, enterprises must:
- Set up endpoint security effectively to thwart attacks
- Regularly update the virus databases – this would be more effective with adaptation of cloud security
- Schedule frequent scans to detect any malware infiltration
Compelling Reasons to Adopt Cloud Security
Cloud-based security is easier to manage. Updates, monitoring, etc.., can be done from the cloud.
If you are an MSP then ensuring proper security of client endpoints can only be done through cloud security and remote monitoring and management. Update management – operating system, applications and security product – can be torturous if not done through the cloud management.
Endpoint security product developers/ antivirus product companies usually share their discovery of malware in a global repository. This combined effort makes information about new malware available quickly to those who access the database.
Cloud Security Beneficial
The benefits of cloud security are huge when compared to using traditional local system-based antivirus security solutions. Present day zero-day malware requires a faster response. And to ensure effective enterprise security it is best to opt for cloud security with a default-deny approach that can thwart evolving present-day zero-day exploits.
