29. Cybersecurity Interview Questions 14 14 What are Salted Hashes? www.edureka.co/cybersecurity-certification-training CYBERSECURITY CERTIFICATION COURSE

30. Cybersecurity Interview Questions 14 14 What are Salted Hashes? Salt is a random data. When a properly protected password system receives a new password, it creates a hash value of that password, a random salt value, and then the combined value is stored in its database. This helps defend against dictionary attacks and known hash attacks. Example: If someone uses the same password on two different systems and they are being used using the same hashing algo, the hash value would be same, however if even one of the system uses salt with the hashes, the value will be different www.edureka.co/cybersecurity-certification-training CYBERSECURITY CERTIFICATION COURSE

31. Cybersecurity Interview Questions 15 15 How identity theft could be prevented? www.edureka.co/cybersecurity-certification-training CYBERSECURITY CERTIFICATION COURSE

34. Cybersecurity Interview Questions 16 16 How can you prevent Man In The Middle (MITM) attack? MITM attack happens when a communication between two parties (systems) is intruded or intercepted by an outside entity. The first method to prevent this attack would be to have encryption (preferably public key encryption) between both the parties. This way, they both will have an idea with whom they are talking because of the digital verification. Second method, to prevent this, it is best to avoid open Wi-Fi networks and if it is necessary then use plugins like HTTPS, Forced TLS etc. www.edureka.co/cybersecurity-certification-training CYBERSECURITY CERTIFICATION COURSE
