What is Hashing in Cyber Security and How Does It Work?

Hashing refers to the transformation of a string of characters into an easier-to-remember fixed-length value or key. Hashing can be used to index and retrieve items from a database. The shorter key takes less time than the original value to locate an item. Hashing is also possible in many encryption algorithms.

What is Hashing in Cyber Security? – The Hash Function is also known as Hashing. This term is derived from the idea of the resulting hash value being a ” Mix It Up” version of the represented value.

What is Hashing in Cyber Security | Different Hashing Techniques

There are three main ways to deal with hash clash. These are:

  • Chaining
  • Rehashing
  • Separate chaining

1. Chaining

This hashing technique generates a link listing of items whose keys share the same value. This link list can be used to search the key you are looking for. This requires you to add a link field for every table position. There are three types of Chaining.

  • General Coalesced Hshing This is an extension of the coalesced chaining technique. This method adds positions to the hash table that can be used to list nodes at collision time.
  • Standard Coalesced Hshing
    This is the easiest. Chaining methods are. It decreases the number required probes to complete a failed search. It performs deletion without any negative impact on efficiency.
  • Varied Insertion Coalesced Hashing

Chaining is the combination of general and standard. Coalesced ishing. This method inserts the colliding items into the list immediately after the hash position, unless the list developing at this position contains a cellar element.

2. Rehashing

This technique uses a secondary function for hash. You can apply the rehash function successively until you find a spot where an item can fit. The rehash function can be used again to locate the item if it is not in use.

3. Separate chaining

Items cannot be inserted larger than the size of the table. Sometimes, space is wasted due to excess space. To resolve conflicts, separate chaining is possible. This is how it works. Hashing maintains separate link listings for records whose keys contain a specific value. This technique places items ending with a particular number in a separate link list. The 100’s, 10’s, and 1000’s are not taken into consideration. Pointer to a node indicates its next node. In cases, where there are no additional nodes, the pointer points to the null value. This method of separate chaining has many key advantages:

  • List items don’t have to be kept in the same storage area.
  • It allows for traversal of items in hash-order
  • Don’t worry about having too many items.

What’s salting?

This is a very common concept in password hashing. This is basically a unique value that can added to the end password to create new hash values. This adds an additional layer of security to the hashing process. This is particularly useful for brute force attacks. Brute force attacks occur when a botnet attempts every combination letter and number until it finds the password. Salting can also be known as salt. Salting is the process of adding salt to a password’s end. washing could mean that you have actually hindered the password cracking process.

What can be done to provide web protection?

Layers of security can also be called cWatch security. This security intelligence service protects web apps and networks against various threats.

cWatch runs regular malware scanning of your domains, and automatically removes malicious code if detected. The Content Delivery Network service increases site performance by delivering web contents from the nearest data center to your visitor.

The cWatch service logs every event that occurs on your domains in order to detect new attack vectors. These logs enable the Comodo Security Operations Center dynamically to design and to apply firewall rules that counter the latest threats.

The console dashboard immediately informs you of your site’s health and any security-related incidents. cWatch can also send you threat notifications via email, phone, or SMS.

Comodo’s Web Application Firewall, (WAF), offers military-grade protection against SQL injections bottraffic, hackers, as well as other threats. You can also make your own firewall rules.

Every week, cWatch scans can be run to identify the top 10 vulnerabilities and other known WordPress vulnerabilities.
