The Triple DES Intro: Triple Data Encryption Standard

Feb 21, 2023 By Muhammad Raza In Splunk
Triple Data Encryption Standard (Triple DES) is a symmetric block cipher-based cryptography standard that uses fixed length keys with three passes of the DES algorithm. As a symmetric cryptographic scheme, DES implementations rely on the same secret keys shared between the sender and the recipient. As we’ll see later, Triple DES was developed as a way to prevent man in the middle attacks. Let’s take a look at Triple DES — and we’ll start first with DES.

Introduction To Key Management

Feb 21, 2023 By Guest In Splunk
Cryptography is used to secure data at rest, stored in servers, and in motion, transmitted over the network. Cryptography involves mathematical operations that convert the original plaintext into an unintelligible ciphertext (encryption) and the reverse process, converting ciphertext to plaintext (decryption). Cryptographic algorithms apply these algorithms in combination of keys, which serve as a secret knowledge to complete the algorithmic operations correctly.

Phishing Scams & Attacks: What To Expect in 2023

Feb 16, 2023 By Guest In Splunk
A form of social engineering, phishing is an online situation where the adversary tricks the victim into sharing sensitive information or installing a malware payload into their systems. Today, phishing is the most prevalent cybersecurity threat in the digital world, with the victim count totaling well over 323,000 unsuspecting Internet users. That’s a 34% increase year over year — and that’s why we’re taking a look at this concerning trend here.

Honeypots Explained: Hitting Hackers Where It Hurts

Feb 16, 2023 By Guest In Splunk
In the world of cybersecurity, honeypots are a unique mechanism. They exhibit no business value, no production value. In fact, any or all interactions with the honeypot are expectedly anomalous and unauthorized. Honeypots are nothing more than a trap set up to lure cybercriminals into believing that they have accessed legitimate and high value computing resources within your network.

How Intrusion Detection Systems (IDS) Work: One Part of Your Security Arsenal

Feb 14, 2023 By Muhammad Raza In Splunk
All cyberattacks that violate the confidentiality, integrity and availability (CIA) of the network and data demonstrate some form of anomalous behavior. The starting point of this behavior may be an unauthorized intrusion into the network and, then, unauthorized use of the resources contained within the network. If you can identify an unauthorized network intrusion attempt, you can maintain the CIA of your data assets and network resources.
