Evaluating New Cisco IoT Security Course

A new course called IoT Security will be available soon. With BiASC we are currently evaluating this course, which is still under limited availability.

What is IoT Security about?

Security is one of the key pillars in the forces of digital disruption that enable digital transformation in every industry. At the same time, the enormous increase of connected IoT devices is not only enabling the digitization of industries, but also increases the landscape of possible security threats. The IoT Security course provides the learner with introductory skills to perform Vulnerability and Risk Assessments on IoT solutions in a specific business context. Students who complete the IoT Security course will be able to assess, research, and provide risk mitigation strategies for common security vulnerabilities in IoT systems. Students seeking a career in the rapidly growing IoT and Security domains will learn practical tools for evaluating security vulnerabilities in IoT solutions, perform threat modeling, and use risk management frameworks to recommend threat mitigation measures.

Research practice and ethical hacking

As in the CyberOperations course students have to accept the ethical hacking agreement.

One of the practice labs is with Shodan explained on the SANS Penetration Testing Website. Also Kali Linux will be used.

Shodan is a search engine that takes a distinct departure from most Internet search engines. Instead of searching through content intentionally served up and delivered to web browsers, Shodan allows us to search for Internet-connected devices.

Next Steps

If instructors in Belgium are interested, we will organise an IoT Security initial traning between October and December 2018. Please send a mail to <yvan@biasc.be> if you would like to receive more information

 

 

Cisco ASA NAT – Configuration Guide

The Cisco ASA and Cisco ASA-X firewalls provides nearly infinite flexibility in so far as their NAT configuration. From the modularity of using objects, to the simplicity of configuring Auto NAT, to the granularity of Manual NAT, to the precision of NAT precedence  — the ASA can do it all.

This article covers each of these concepts in detail, explaining what they mean, when to use them, and how to apply them. If you read it from start to finish, and were able to follow with the examples and illustrations, then you can decidedly consider yourself an address translation expert on the Cisco ASA platform.

Part 1 – NAT Syntax
Objects - Real and Mapped - Auto NAT  - Manual NAT 

Part 2 – NAT Configuration Examples
Static NAT - Static PAT - Dynamic PAT - Dynamic NAT

Part 3 – Advanced NAT
Policy NAT - Twice NAT - NAT Precedence - Identity NAT

Here is the complete guide: http://www.practicalnetworking.net/stand-alone/cisco-asa-nat/

Botnet explained in CyberSecurity Operations

After the CyberSecurity Operations course you will be able to analyse and explain the actions of a botnet.

A botnet consists of a group of "zombie" computers that run robots (or bots) and a master control mechanism that provides direction and control for the zombies. The originator of a botnet uses the master control mechanism on a command-and-control server to control the zombie computers remotely using IRC or other means.

A botnet typically operates as follows:

A botnet operator infects computers by sending them malicious bots. A malicious bot is self-propagating malware that is designed to infect a host and connect back to the command-and-control server. In addition to its worm-like ability to self-propagate, a bot can include the ability to log keystrokes, gather passwords, capture and analyze packets, gather financial information, launch DoS attacks, relay spam, and open back doors on the infected host.

Bots have all the advantages of worms, but are generally much more versatile in their infection vector, and are often modified within hours of publication of a new exploit. Bots have been known to exploit back doors that are opened by worms and viruses, which allows the bots to access networks that have good perimeter control. Bots can infect networks in a way that escapes immediate detection.

The bot on the newly infected host logs in to the command-and-control server and awaits for the commands. Often, the CnC traffic is sent using either IRC, P2P, DNS, HTTP, and HTTPS. When using HTTPS, the CnC traffic will be encrypted using TLS or SSL, making it harder to detect.

Instructions are sent from the CnC server to each bot (zombie) in the botnet to execute actions. When the zombies receive the instructions, they begin generating malicious traffic that is aimed at the victim. Zombies mostly run a covert channel to communicate with the command-and-control server that the attacker controls.

Typical Attack Compromising a Victim's Computer

In the new CCNA CyberSecurity Operations course you learn how to understand attack patterns and how to deal with it as a network defender. Only six steps are necessary to start malicious activity in which a command and control (C2) server is involved. In the image above you see a typical  network attack in which a victim's computer is being compromized step by step.

VERIS Framework for CyberSecurity Incidents

- - -

How to describe security incidents is an important part in the CCNA CyberSecurity Operations course.
URL: http://veriscommunity.net/index.html

VERIS means"Vocabulary for Event Recording and Incident Sharing"

• Vocabulary for event recording and incident sharing
• Common language for describing security incidents in a structured and repeatable manner

 The VERIS Community Database (VCDB) is an open and free repository of publicly-reported security incidents in VERIS format.

Common Attack Pattern Enumeration and Classification (CAPEC™)

In the CyberSecurity Operations course there are mutiple descriptions of attack patterns. CAPEC is a good source to understand cyber attacks.

The objective of the Common Attack Pattern Enumeration and Classification (CAPEC™) effort is to provide a publicly available catalog of common attack patterns classified in an intuitive manner, along with a comprehensive schema for describing related attacks and sharing information about them.

Some Well-Known Attack Patterns:
HTTP Response Splitting (CAPEC-34) Session Fixation (CAPEC-61) Cross Site Request Forgery (CAPEC-62) SQL Injection (CAPEC-66) Cross-Site Scripting (CAPEC-63) Buffer Overflow (CAPEC-100) Clickjacking (CAPEC-103) Relative Path Traversal (CAPEC-139) XML Attribute Blowup (CAPEC-229)

 For an experienced security engineer, the value of an attack pattern is not that it presents a new idea, but that it helps communicate a common idea with others. If you and a colleague all know what clickjacking is, then you can communicate a lot by saying: "This attack leverages clickjacking."

This information when captured in such a formalized way can bring considerable value to security considerations for cyber-enabled capabilities through all phases of the development lifecycle and other security-related activities, including:

• Requirements Gathering – Identification of relevant security requirements, misuse and abuse cases.
• Architecture and Design – Provide context for architectural risk analysis and guidance for security architecture.
• Implementation and Development – Prioritize and guide review activities.
• Testing and Quality Assurance – Provide context for appropriate risk-based and penetration testing.
• System Operation – Leverage lessons learned from security incidents into preventative guidance
• Policy and Standard Generation – Guide the identification of appropriate prescriptive organizational policies and standards.

Of course, attack patterns are not the only useful tool for building secure cyber-enabled capabilities. Many other tools, such as misuse/abuse cases, security requirements, threat models, knowledge of common weaknesses and vulnerabilities, and attack trees, can help. Attack patterns play a unique role amid this larger architecture of security knowledge and techniques.
