Course 7: Incident Detection and Response Welcome to course seven, Incident Detection and Response. Having an intruder inside your systems for months unnoticed by your systems, administrators, security specialists, and end-users is tantamount to giving the intruder, the keys to your business or organization. In many cases, organizations discover that they have been subjected to a data breach when they are told by others that their private data has been offered for sale on the dark web. Many leading voices within the security profession state that we all must do better to detect the intruders in our myths. Many people even say that detecting intruders should be the priority for security professionals. Ransomware attacks have become a big business involving not only large scale extortion attacks, but also the sell of ransomware attack tools and services, as well as the exploitation of any data ex-filtrated during the breach. Government officials and industry professionals worldwide have been raising their voices about this new and very troubling variant in the business model of advanced persistent threat or APT attackers. In this chapter, we'll focus on intrusion and incident detection. Many of the tools, techniques, technologies, and ideas, you'll see here have already been examined in previous chapters. This course brings them together and begins by discussing the central theme of detecting the intruder. Model one uses the concepts of precursors and indicators, the signals that give us advanced warning and a genuine alert about a risk event and the indicators of compromise concept which are those signals that we're certain can only mean a hostile agent has gained access. Module two will extend these ideas and concepts around the idea of what to do after you've discovered a possible intrusion, expanding your understanding of incident response. Module three continues with a deeper look at supporting forensic investigations. Forensics is an evidence-based process of logically and dispassionately reasoning about a situation or an event. It's your inner child, looking at something and asking questions. Then following each of those questions with more questions, letting the facts that you find frame and shape your growing understanding of what happened, how why and where, who did it and what impacts it may have. With these questions answered you can circle back to reviewing risk mitigation controls to see which if any, need to be modified, replaced or augmented.

These underlying policy enforcements mechanisms help introduce basic functional protections, starting with authentication methods. Learners will be introduced to a series of different authentication solutions and protocols, including RSA SecureID and Kerberos, in the context of a canonical schema.   The basics of cryptography are also introduced with attention to conventional block ciphers as well as public key cryptography. Important cryptographic techniques such as cipher block chaining and triple-DES are explained. Modern certification authority-based cryptographic support is also discussed and shown to provide basis for secure e-commerce using Secure Sockets Layer (SSL) schemes.

Welcome to course 4 of 5 of this Specialization, Network Security. In this course, we will look at computer networking and securing the network. In today’s world, the internet connects nearly everyone and everything, and this is accomplished through networking. While most see computer networking as a positive, criminals routinely use the internet, and the networking protocols themselves, as weapons and tools to exploit vulnerabilities and for this reason we must do our best to secure the network. We will review the basic components of a network, threats and attacks to the network, and learn how to protect them from attackers. Network security itself can be a specialty career within cybersecurity; however, all information security professionals need to understand how networks operate and are exploited to better secure them. After completing this chapter, the participant will be able to:  Explain the concepts of network security. - Recognize common networking terms and models. - Identify common protocols and ports and their secure counterparts. - Identify types of network (cyber) threats and attacks. - Discuss common tools used to identify and prevent threats. - Identify common data center terminology. - Recognize common cloud service terminology. - Identify secure network design terminology. - Practice the terminology of and review network security concepts.
