Security At The Initial Level

The way security breaches are happening, we must think of a solution which could support a robust IT Security solution. In the Covid19 situations, the number of remote and roaming employees working has increased tremendously and the threat of IT Security has gone high. While thinking about the security of the users who are working from remote, there is a bit of room for worry in terms of how to secure them. The fact is that attackers were already targeting this weak point in security before the massive influx of new remote workers.
Let’s take the case of the manufacturing industry. In manufacturing companies, many of the users are hardly aware about the importance of IT Security and the kind of threat that prevails across the internet. The thing about having different kinds of employees is that some are very young and Junior are not able to understand the impact and challenges. On the other hand, some of them are mature and senior level may understand and sincerely follow the guidelines. The challenge is to manage the scenario by managing each one. There is a strong need to secure all these new remote web traffic and to do it quickly and efficiently.
So now there is a powerful and scalable way to secure your remote and roaming user web traffic. How do you get that traffic to the cloud service? That is where the Cisco AnyConnect client fits in. Cisco released a new version of the AnyConnect client that is fully integrated with the Umbrella SWG.
Security at DNS Level
By implementing the Cisco Umbrella, we can manage the Security at the DNS Level. Having a simple solution that demands very less configuration efforts can make the things simple and easy. It provides the first line of defense against threats on the internet. Sometimes predictions are important, though that we can have the preventive activities aligned. Cisco Umbrella solution has that capability, and it can predict the situation based on the study.
After implementing the Cisco Umbrella, one thing that is good for organizations is that we do not have to worry about the threatful DNS. It becomes this umbrella’s job to take care of that. According to Cisco, they have their on-Cloud servers which are continuously checking the domains’ authenticity. Based on authenticity verification, they resolve the DNS. Even if you are working from home, there is one client installed at your end point which will take care of DNS resolution authenticity. Then again, discovering the risky domains becomes a job of the Cisco Umbrella.

The appliances usually wait until the malwares and viruses reach to then detect and prevent. But since the Cisco Umbrella comes with DNS control-based technology, it has the capability to detect malwares and viruses before they reach your endpoint devices. Cisco Umbrella has also released a cloud-native secure web gateway (SWG) which provides a broad set of web traffic control and security (and works with both Cisco and third-party VPNs). It includes antivirus and malware scanning, sandboxing, content and file type controls, application visibility and control, HTTPS/SSL decryption, and full URL level reporting. SWG capabilities are available as part of the Umbrella SIG along with firewall, DNS-layer security, cloud access security broker (CASB) functionality, and interactive threat intelligence in one cloud-delivered solution.
Now the challenge actually also branches into one more question: how to protect against Phishing during Covid19 Situation? If I may take an example of solving this situation, something that we have successfully accomplished in our organization is that we have implemented Cisco Umbrella and OpenDNS services to ensure that we are protecting our users against pandemic themed cyberattacks.
Prevent Connectivity Before and During the attack
Generally, Cisco Umbrella takes care of Web and email-based infection, malware, exploit kit, phishing, web link etc and blocking the malicious domain. It has predictive IP space modelling, Spike rank model, Natural Language processing rank model, DHCP Server, DNS Server, Virtual appliances - Route traffic and ID’s via DNS. For roaming users, AnyConnect clients take care of threats and infections based on DNS controlled connections.
