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

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

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

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 [https://www.rapid7.com/fundamentals/siem/],

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.

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?

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.

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

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

built out new features, refined others, and overall fortified our solution.
We validated that security teams not only want to save time, increase

The 3 Things You Need in Place to Successfully Leverage Security Orchestration and Automation
In a time where security is becoming a board-level discussion and threats are
affecting not only big businesses, but small ones too, many security teams are

massive efficiencies and a proactive security posture. The way to achieve both
of those simultaneously is through security orchestration and automation
