How To Protect SSH and Apache Using Fail2Ban on Ubuntu Linux

Synopsis Fail2Ban is a free and open source intrusion prevention software tool written in the Python programming language that can be used to protects servers from different kinds of attacks. Fail2Ban works by continuosly monitoring various logs files (Apache, SSH) and running scripts based on them. Mostly it is used to block IP addresses that are trying to breach the system’s security. It can be used to block any IP address that are trying to make many illegitimate login attempts. Fail2Ban is s

Detection and Analysis Phase of Incident Response Life Cycle of NIST SP 800-61

Synopsis In the series of articles titled “Incident Response Life Cycle in NIST and ISO standards” we review incident response life cycle, as defined and described in NIST and ISO standards related to incident management. We introduced these standards in the first article in this series [/2017/01/11/recommendations-for-incident-response-team-included-in-nist-special-publication-800-61/] .

Understanding GRE (2/2)

Synopsis: In the last post [/2017/01/30/understanding-gre/], I talked about the GRE tunnels, it’s Class of Service and the Firewall Filters it offers.  The next step is to learn about the simplest way to configure a tunnel between two sites using GRE.  This article aims to give understanding about the Configuration of GRE Tunnels for Juniper Networks. Pre-requisites: Before we go in the actual configuration, here is a checklist that you must have before configuring your GRE tunnel between sites

Basics of IPsec

What is IPsec? IPsec is a framework of related protocols that secure communications at the network or packet processing layer. It can be used to protect one or more data flows between peers. IPsec enables data confidentiality, integrity, origin authentication and anti-replay. Why was IPsec created? There was a dire need of communicating data packets securely over large public WAN (mainly Internet). The solution was development of many networking protocols among which IPsec is one of the most de

InfoSec Valentines: Show a Security Nerd How Much You Care

It's no secret that we ❤️ security defenders. And while we typically show our love through helpful insights and technique-driven articles, there's just something about this time of year that makes us want to display it in an entirely different fashion. We present to you infosec valentines! We know this isn't a new phenomenon [https://twitter.com/search?q=%23infosecvalentines&src=typd], but with all the doom and gloom that winter brings, creating and sharing infosec valentines got us excited.

Managing Third-Party Vulnerabilities with Security Orchestration and Automation

Industry-best practices dictate that companies should keep software up-to-date as part of maintaining a healthy security posture. Yet many companies struggle with vulnerability management, especially when it comes to vendor and third-party software. Third-party vulnerability management is often a balance between ensuring that critical bugs get reviewed and applied quickly, while reducing the risk of downtime due to a potentially unstable patch. When it comes to managing a complex vendor vulnera

Getting the Most Value out of Your Security Products

We know how difficult it can be to get the full value from security products — especially when many don’t connect with others easily. Some products take too long to fully configure; others suffer from feature bloat, making them difficult to use; and some, sadly get forgotten, simply collecting dust on the shelf. Here’s how to better utilize each security tool you already have so you can maximize that investment and get more done, faster. Make a Plan Before you get started, take a moment to de

Fine Tuning Your Intrusion Detection System to Minimize False Positive Alerts

Monitoring and protecting your company’s assets is one of the most important jobs you can perform. It can be tedious sometimes, but overall it can have the biggest impact to the business if compromised. Having alerts set up in your SIEM, IDS and FIM solutions can ultimately keep you on track. Eliminating false positive results can be a whole different story. Being able to pick out false positives from your environment is a huge undertaking but grants great reward. Below are some steps that you

Understanding Generic Routing Encapsulation (GRE) (1/2)

Synopsis To transport packets in a private and secure path over a public network, we use the process of encapsulating packets inside an IP encapsulation protocol. GRE follows this protocol and sends packets from one network to another through a GRE tunnel. In this blog, we will understand what is encapsulation, the CoS of GRE and firewall filters in GRE. Understanding GRE – Generic Routing Encapsulation What is encapsulation? The general internal representation of an object or data or packet is

How to Automate Response to Endpoint Threats with Sysdig Falco, Splunk, Duo, and Komand

Many security teams use endpoint threat detection solutions to detect and respond to threats like malware, credential theft, and more. In a common architecture using a SIEM or Log Management solution, alerts from endpoint detection products can be managed and correlated with telemetry from other solutions or logs, and validated: Generally, a human being has to get involved anywhere from the third step forward. Can we do better? Using a typical architecture with a real endpoint threat detecti

Two Factor Authentication Methods and Technologies

Synopsis Authentication is a critical step that forms the basis of trust on the Internet or any network based transactions. To state simply it verifies that the person or entity is who they claim to be. However authentication mechanisms are constantly under attack. Two Factor Authentication is an evolution to counter these security threats. This tutorial takes a look at various types of authentication methods and technologies behind them. Different Types of Authentication Factors Three distinct

The Most Repetitive Tasks Security Analysts Perform

It’s not very productive to come into work day in and day out just to perform the same task dozens of times when you were trained to hunt threats and remediate complex problems. The repetition of rote tasks like IP scoring, alert monitoring, and URL lookups can be fatiguing and dissatisfying, which, as major security breaches show [http://www.darkreading.com/attacks-and-breaches/target-ignored-data-breach-alarms/d/d-id/1127712] , can cause alerts to slip through the cracks and threats to get in

Introducing Komand’s Security Orchestration and Automation Platform

It was just a few months ago when we launched our beta program. And with beta users working within our security orchestration and automation platform [https://www.rapid7.com/solutions/security-orchestration-and-automation/], we built out new features, refined others, and overall fortified our solution. We validated that security teams not only want to save time, increase productivity, and streamline operations, they also need a tool that would allow them to add automation to their security work
