Disaster Recovery

Disaster recovery preserves business continuity and expedites the recovery process when a firm is hit by a natural catastrophe thereby reducing loss. The purpose of disaster recovery is to limit the effect of the incident on the company while maintaining customer service standards.

Advanced Persistent Threat Lifecycle

An advanced persistent threat (APT) is a type of attack campaign in which an unauthorized user gains access to a network and remains there undetected for a prolonged period of time. These attacks are often orchestrated by highly skilled and well-funded adversaries and are designed to achieve specific objectives, such as espionage or data theft. While APT attacks can be difficult to detect and defend against, there are a number of steps organizations can take to reduce their risk of becoming a victim.

Understanding the different types of scan you can perform with Nmap

Port scanning is the method of enumerating open ports and services by delivering a series of messages. Port scanners identify active hosts and scan their ports by manipulating transport layer protocol flags. Administrators and users may accidentally keep unnecessary open ports on their computers. An attacker can take advantage of such open ports for malicious purposes.

Common Code Injection Vulnerabilities

Injection attacks are a type of attack that allows attackers to execute malicious code on a server by injecting it into a web application. This can be done through user input, such as via a form field or URL parameter. Once the code is injected, it can be executed by the server, resulting in the attacker gaining access to sensitive data or damaging the server. Injection attacks are a serious threat to web applications and can be difficult to prevent.

How to Stop SMTP Open Relays

SMTP stands for Simple Mail Transfer Protocol. This protocol allows email messages to be sent from one computer to another. The Internet was originally designed to allow computers to communicate directly with each other, without human intervention. In order to send emails, you need to know the address of the recipient (the person or company who receives the message).

A Note on Linux Directory Structure for DFIR

When you want a glass of water, you will head over to your kitchen to get it. You know the layout of your house, you know that the kitchen would have water – so you navigate there to get what you need. In the same way, to be able to perform Linux Forensics, it would be great to know about the layout of files on a Linux system and have an idea about where critical log files are stored. This blog post introduces you to the main directory structure on Linux systems. Knowing what information is held within the various directories will help a forensic examiner know where to look, while searching for evidence.

Introduction to Honeypots, Honeynets, and Padded Cells

Honeypots, honeynets, and padded cell systems are all terms for a family of sophisticated security solutions that go beyond ordinary intrusion detection. To understand why these technologies aren’t more frequently utilized, first understand how they vary from typical IDPs.

Introduction to Threat Modeling

Every organization has several valuable assets that must be safeguarded. The assets can be tangible, such as computers, laptops, and network equipment, or intangible, such as information, data, programs, and so on. As the number of cyber-attacks increases around the world, the focus on cyber security is shifting from reactive to proactive methods. A proactive cybersecurity strategy is a preventative strategy that seeks to discover any vulnerabilities and threats surrounding our assets before they have an opportunity to compromise the security of our assets. Threat modeling is one of the most widely utilized proactive methodologies in the creation of secure systems and applications. This article will explain what threat modeling is and how you can leverage it to improve your organization’s security posture.

A gentle introduction to digital forensics on Linux

Have you watched movies where skilled cyber operators have black windows open in their computers, with coloured text scrolling through? They type some content in the black screens and magical stuff happens. Have you wondered how they go about doing all that? What applications may they be using? All those tasks can be performed on Windows, Linux-based and Mac operating systems. For now, let us focus on the Linux-based ones. This blog post introduces some basic concepts about Linux-based computers and discusses how Linux proves useful in the DFIR domain.

Understanding Security Information and Event Management Systems (SIEMs)

Security Information and Event Management (SIEM) is a software system that combines Security Information Management (SIM); an automated process of collecting data of log files into a central archive, and Security Event Management; a type of computer security that monitors, correlates and notifies users of events as they occur in a system; to collect, analyze and report on all security-related events happening in an organization. The goal is to provide real-time monitoring of security devices such as firewalls, antivirus software, intrusion detection systems, and other network-based systems for potential threats. This post will explore the benefits of implementing a SIEM in your business by highlighting some of its most important features.
