Succeeding with UEBA in a Rapid Data Growth World

With the rapid expansion in both scale and variety of technologies in modern business systems, there comes a need to further secure those technologies to prevent nefarious actors from causing havoc. The expanding data landscape creates a much larger attack surface for bad actors to exploit, and as a result leaves many organizations at risk from theft, fraud or other undesirable behavior.

The importance of event correlation techniques in SIEM

Event correlation tools are a fundamental instrument in your toolbox to detect threats from all sources across your organization in real time. A wise use of the right event correlation techniques through log management and analysis is the cornerstone of any reliable security information and event management (SIEM) strategy – a strategy that focuses on prevention rather than reaction.

Mitigate Cyber Risk From Email With the Falcon LogScale and Mimecast Integration

Email is the top initial attack vector, with phishing campaigns responsible for many damaging cyber attacks, including ransomware. Being able to search Mimecast email security logs in CrowdStrike Falcon® LogScale (formerly known as Humio), alongside other log sources such as endpoint, network and authentication data helps cybersecurity teams detect and respond to cyber attacks.

How to Ingest Data into Falcon LogScale Using Python

This post covers how to ingest data into CrowdStrike Falcon® LogScale from your MacOS platform using Python. This guide is great for setting up a one-node proof of concept (POC) so you can take advantage of LogScale’s free trial. Before you can write your ingest client, you must prepare a good foundation. That means preparing your MacOS instance via the following steps: Ready? Let’s get started.

Ransomware Families Bringing Home the Biggest Security Risks

Ransomware is the type of malware that locks you out of your own computer until you pay a ransom. This digital extortion is one of the most serious security threats facing the Internet today. Ransomware not only impacts unsuspecting Internet users, but business organizations, government institutions and even critical services such as utility, healthcare and emergency facilities. Ransomware has been around for many years.

Coffee Talk with SURGe!

Grab a cup of coffee and join David Bianco, Shannon Davis, and Audra Streetman for another episode of Coffee Talk with SURGe. The team from Splunk will discuss the latest security news, including: David Bianco and Shannon Davis also competed in a charity challenge comparing the pros and cons of the Pyramid of Pain, a conceptual model created by David to order indicators of compromise (IOCs) by the pain they cause adversaries when the IOCs are not available to them.

The Triple DES Intro: Triple Data Encryption Standard

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

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.

Threat Hunting vs. Threat Detecting: Two Approaches to Finding & Mitigating Threats

Threat hunting and detection are two major prevention strategies in modern cybersecurity systems. Both strategies help identify potential threats to the organizations — though they take different approaches to threat identification. This article explains the difference between threat hunting and detection, so you know what to focus on for your organization’s cybersecurity strategy.

Cyber Security: Understanding the 5 Phases of Intrusion

Here at Graylog, we have recently had an increase in conversations with security teams from leading companies. We want to share our key findings with the Graylog community. The good thing is that cybercriminals use a methodical approach when planning an attack. By understanding their process and knowing your network, you will be better prepared and able to stay one step ahead.
