Enterprise Defenses

מק"ט: #7516 | משך קורס: 32 שעות אק'
| מספר מפגשים: 4

Is your organization vulnerable? How secure is your domain? Can any malware run on your endpoints? Why patch? Should you limit your users? How can you limit them? Hardening an enterprise is a complicated task. Keeping it secured and updated is a long process. Vulnerable operating systems and applications are what attackers look for. The student learns about domain attacks and the meaning of lateral movement. Vulnerability scanning is crucial for understanding the security level of your domain. The next step is to patch and update the application in order to remove the vulnerability. Users can usually perform more tasks than they need to. The student learns how to create and deploy a hardened image. This includes creation, planning, deep understanding of processes in the organization’s network and the importance of application whitelisting.
