Gartner Magic Quadrant for Web Application Firewalls (2018,2017,2016)

A web application firewall (WAF) is an application firewall for HTTP applications. It applies a set of rules to an HTTP conversation. Generally, these rules cover common attacks such as cross-site scripting (XSS) and SQL injection.

While proxies generally protect clients, WAFs protect servers. A WAF is deployed to protect a specific web application or set of web applications. A WAF can be considered a reverse proxy.

According to Gartner, by 2023, more than 30% of public-facing web applications will be protected by cloud web application and API protection (WAAP) services that combine distributed denial of service (DDoS) protection, bot mitigation, API protection, and WAFs. This is an increase from fewer than 10% today.

2018

On August 2018, Gartner’s released their latest Magic Quadrant report for Web Application Firewalls. Only Imperva and Akamai are in the Leaders quadrant. F5 has been moved out from Leaders quadrant to challengers. Other vendors , such as Fortinet, Cloudflare, Barracuda, Citrix, are not changed much and still in challengers. Oracle and Radware are in Visionaries quadrant.

Install T-Pot into Google Cloud Platform VM Instance

T-Pot is a honeypot platform built on Ubuntu with Dock technology. Latest version is 17.10 and OS is Ubuntu 16.04. The minimum system requirement is at least 2GB RAM and 40GB disk space.

There are some other posts online to show how to install T-Pot into cloud virtual machine instance. Unfortunately, I failed so many times and got a error message 'could not find authrized_keys at .ssh folder'. Eventually I found issue is with the user I were using. If I create a new user and add it into sudo group, and install T-Pot after log in as that new user, the installation process is quite smooth.

Here is all steps I did. Hopefully it helps when you try this awesome honeypot.


1. Create a VM


2. Update your Ubuntu instance

Cisco Web Security Appliance (WSA) S190 - Web GUI

Cisco® IronPort Web Security Appliance (WSA) offers malware protection, application visibility and control, acceptable use policy controls, insightful reporting and secure mobility to enterprise network. 

The Cisco IronPort WSA is a forward proxy that can be deployed in either Explicit mode (proxy automatic configuration [PAC] files, Web Proxy Auto-Discovery [WPAD], browser settings) or Transparent mode (Web Cache Communication Protocol [WCCP], Policy-Based Routing [PBR], load balancers). WCCP-compatible devices, such as Cisco Catalyst® 6000 Series Switches, Cisco ASR 1000 Series Aggregation Services Routers, Cisco Integrated Services Routers, and Cisco ASA 5500-X Series Next-Generation Firewalls, reroute web traffic to the Cisco WSA. The Cisco WSA can proxy HTTP, HTTPS, SOCKS, native FTP, and FTP over HTTP traffic to deliver additional capabilities such as data-loss prevention, mobile user security, and advanced visibility and control. Cisco provides hardware appliances (Cisco S690, Cisco S690X, Cisco S680, Cisco S390, Cisco S380, Cisco S190, Cisco S170) and virtual appliances WSAV (S000v, S100v, S300v) for different requirements. In this post, S190 will be used to show the how web gui looks like.
The Cisco S190 appliance is typically installed as an additional layer in the network between clients and the Internet.

CPUs
SMB and Branch
S190
1.2TB
(2x600 GB SAS)

Depending on how you deploy the appliance, you may or may not need a Layer 4 (L4) switch or a WCCP router to direct client traffic to the appliance.
Deployment options include:

  • Transparent Proxy—Web proxy with an L4 switch 
  • Transparent Proxy—Web proxy with a WCCP router 
  • Explicit Forward Proxy—Connection to a network switch 
  • L4 Traffic Monitor—Ethernet tap (simplex or duplex)

How to Find Out Windows Process Sending Traffic, Especially ICMP Packets

There are a number of different ways to find out which process is sending tcp / udp traffic in computer systems, but not much for icmp traffic.

Here is a summary for the ways to do it.

1. Install a local firewall

You could always try installing a firewall that blocks outgoing traffic or use the Windows Firewall. When the traffic is generated, it could prompt you asking whether you want to allow it or not. In many cases, it will tell you what application is generating the traffic.

NSS Labs NGFW Security Value Map Report (2018, 2017, 2016, 2014, 2013, 2012, 2011)


The NGFW is the first line of defense to protect against today’s evolving threats and is a critical component of any defense-in-depth strategy.  The NSS Labs NGFW test methodology has evolved from the previous testing to reflect the threat landscape and therefore, this latest testing includes SSL inspection.  This is an important key test factor because most vendors see huge performance impacts when SSL is turned on, preventing them from publishing SSL performance on their datasheets.  With the expanded use of secure sockets layer (SSL)/transport layer security (TLS) in the traffic traversing the modern network, an NGFW must be able to inspect encrypted content. NSS Labs evaluated firewall products with 190 different evasion techniques, more than 2,000 exploit tests and throughput tests.

NSS Labs regularly released NGFW Security Value Map™, Comparative Analysis Reports, and Product Analysis Reports.  These results help guide security professionals in the enterprise to make informed decisions when evaluating the many offerings in the industry.

NSS Labs designed the test to focus on the following four areas:
  •     Security effectiveness
  •     Performance
  •     Stability
  •     Total Cost of Ownership (TCO)

Steps to Troubleshoot an Infected Computer

Today received a report from user, computer is slow and seems have been infected with unknown virus or malware. No special symptoms except slow.

1. Check task manager and resource monitor

There is a process smss.exe which description is "Microsoft ? Console Based Script Host " using almost 75% CPU all the time.

From task manager, I found system was rebooted a couple of hours ago at very early morning and user was not around.

Also, no matter how you ended this process, it will come back in 10 seconds and take your CPU away and use about 4M your memory.

Install OpenVAS on Ubuntu


OpenVAS is a framework of several services and tools offering a comprehensive and powerful vulnerability scanning and vulnerability management solution. The framework is part of Greenbone Networks' commercial vulnerability management solution from which developments are contributed to the Open Source community since 2009.

1. Install dependencies

OpenVAS Virtual Appliance / GreenBone Installation

OpenVAS Framework
The GSM Community Edition is a derivate of the GSM ONE and allows a quick and easy option on Windows, Linux or Mac to give the solution a trial. No particular know-how is needed.
In contrast to the commercial solution the Community Feed instead of the Greenbone Security Feed is used. Also some management functions like for TLS certificates are not included. Feed updates happen on a regular basis, but the system itself can not be updated. The commercial version can be updated seamless and also includes access to the Greenbone Support.
The Community Edition as well as the GSM ONE are designed for use with a laptop. The full feature set for a vulnerability management process (schedules, alarms, sensors) are only available with the bigger GSM models (see here for an overview) and can be obtained from Greenbone as an evaluation unit.

Metasploit Installation on Windows 7 and 10

The Metasploit Framework (MSF) is far more than just a collection of exploits. It’s an infrastructure that you can build upon and utilize for your custom needs. This allows you to concentrate on your unique environment, and not have to reinvent the wheel. I consider the MSF to be one of the single most useful auditing tools freely available to security professionals today. From a wide array of commercial grade exploits and an extensive exploit development environment, all the way to network information gathering tools and web vulnerability plugins, the Metasploit Framework provides a truly impressive work environment.

Cisco IOS Internet Key Exchange version 1 (IKEv1) Vulnerability and Fix

Cisco IKEv1 is still popular in VPN configuration. Most of my vpn configuration is based on IKE v1 although there are more demands for v2.  I had a post "Cisco Router IKE v2 Site to Site IPSec VPN Configuration" to quickly show what the difference is between v1 and v2, and how to do v2 configuration.  Recently some vulnerabilities scan tools raised a red flag to my IKE v1 configuration.

Symptoms 

There is IKE v1 vulnerability found and it lists severity level high.
