Indicators of Compromise (IoCs): What Are They and How Do They Strengthen Cyber Defense?

IoCs are forensic data threat intelligence teams use to confirm cyberattack occurrences and build cyber-defense strategies. IoCs are critical in identifying system vulnerabilities, and determining how a cyber-crime was executed. While the relevance of IoCs cannot be downplayed in the cyber security space, they are not all that’s needed in building an effective cyber-defense strategy.

Model-Assisted Threat Hunting (M-ATH) with the PEAK Framework

Welcome to the third entry in our introduction to the PEAK Threat Hunting Framework! Taking our detective theme to the next level, imagine a tough case where you need to call in a specialized investigator (even Sherlock depended on Watson from time to time!). For these unique cases, we can use algorithmically-driven approaches called Model-Assisted Threat Hunting (M-ATH). In this post, we’ll look at M-ATH in detail.

Trust Unearned? Evaluating CA Trustworthiness Across 5 Billion Certificates

In the complex world of Internet security, TLS encryption reigns. The powers behind the throne are the Certificate Authorities (CAs) that play a crucial role in verifying websites' identities and regulating the trust we place in those sites. However, understanding the trustworthiness of the CAs themselves can be challenging.

Red Teams vs. Blue Teams: What's The Difference?

Cyberattacks are unauthorized attempts to access data and disrupt your organization's computer systems or networks. It’s reported that 49% of organizations have suffered a data breach over the past two years — it’s possibly higher than that. These data breaches can cause financial loss, reputational damage and legal liabilities. So, organizations develop Red and Blue teams to mitigate the risk of cyberattacks.

Help Safeguard Your SAP Environment with Splunk Security for SAP Solutions

Even though this blog discusses some serious topics related to security of mission-critical SAP applications, why not start it with a fun trivia question? So, here it is: “What does SAP stand for?” As per the company’s website, SAP is an acronym for the organization’s original German name “Systemanalyse Programmentwicklung,” which stands for System Analysis Program Development in English. Founded in 1972, SAP is a global leader in enterprise application software.

Cloud Cryptomining: How It Works & How To Minimize Risk

Cryptomining is essential for creating new cryptocurrencies and functioning blockchain networks. However, the increased complexity of cryptomining drives the need for specialized, cost-effective infrastructure to mine cryptocurrencies. Enter the cloud: Cloud computing has become critical for cryptomining, making cloud cryptomining popular among miners. This article describes cloud cryptomining, its history, and the types of cloud cryptomining.

RSA Algorithm in Cryptography: Rivest Shamir Adleman Explained

RSA is a popular and secure cryptographic algorithm that encrypts and decrypts data. It provides a secure method for transmitting sensitive data over the Internet. While RSA has some vulnerabilities, it is still utilized for various applications, like digital signatures to authenticate the source of a message. This article describes RSA, how it works, and its major applications. It also explains the security vulnerabilities of RSA and how to mitigate them.

Cyberattack Maps Explained: The Value & Limitations of Cyber Attack Maps

While most people understand that cybercrime is rising, it’s challenging to fathom just how widespread it is. In 2007, researchers found there was a cyberattack every 39 seconds. By 2022, those numbers seemed small and innocent in comparison: The sheer scale of attacks makes it a challenge to understand and find emerging threats or identify trends. Cyberattack maps provide visuals that clarify numbers that can be otherwise difficult to understand and bring to light the dark activities online.

Typosquatting 101: Types, Examples & Ways to Protect Yourself from Typosquatting Attacks

Typosquatting goes by many names: URL hijacking, domain mimicry and domain typo-squatting, to name a few. However, they all mean the same thing: malicious attackers register domain names similar to popular websites but with common typos and variations. Typosquatting aims to trick users who mistype the legitimate URL into visiting and using the fraudulent site. It is a widespread practice.

What Is SAML? SAML Authentication & Security Assertion Markup Language Explained

Authentication and authorization are two processes that play a significant role in any web application. These concepts ensure that only trusted individuals are granted access to the resources of the application. Plus, with all the web applications and services we use regularly, it is increasingly difficult to manage credentials for multiple user accounts. SAML technology provides a means for securely logging into multiple applications using a single set of credentials.

APTs in 2023: Characteristics, Phases & Defending Against Advanced Persistent Threats

When it comes to cyber threats, few are as feared as Advanced Persistent Threats. An Advanced Persistent Threat (APT) is a sophisticated, highly targeted and often long-term cyberattack orchestrated by well-funded and highly skilled threat actors. In some cases, they’re even backed by governments: North Korea, Russia and China have all been caught orchestrating APT attacks in the past two years. APTs differ from traditional cyber threats, which are more persistent, targeted, and sophisticated.

Bug Bounty Programs Explained: Proactively Finding Bugs for Enhanced Security

The digital world is a lot like the Old West: lawless criminals are looking to take advantage of any bug, flaw or vulnerability to exploit. To combat the problems from these flaws, many organizations offer bounties to anyone who can find them before cybercriminals. Because bugs can be challenging to spot, bug bounty programs leverage ethical hackers' expertise to spot corporate software's flaws. Some of the largest corporations in the world, including Google, Microsoft, and the U.S.

Hypothesis-Driven Hunting with the PEAK Framework

Picture yourself as a cyber detective, ready to uncover the hidden threats lurking in the shadows of your organization's network. Sounds exciting, right? Well, hypothesis-driven hunting is all about channeling your inner Hercule Poirot to stay one step ahead of adversaries working against you. The PEAK threat hunting framework identifies three primary types of hunts: In this post, we’re going to look at hypothesis-driven hunting in detail.
