Top online cybersecurity courses
Cybersecurity is an in-demand, fast-growing field with a need for qualified employees, offering high median salaries, job opportunities in a variety of sectors, and a challenging, fast-paced work environment.
There are a few ways to think about the kinds of opportunities emerging in cybersecurity including looking at the kind of role played within an organization.
Offensive security refers to penetration testing with a focused scope on finding security vulnerabilities, flaws risks, and unreliable environments. An offensive security practitioner normally follows a systematic approach to evaluate the well-being of both network, applications, and system endpoints.
Offensive cybersecurity usually starts with the reconnaissance and footprinting phase, which involves collecting information about target sites; the information sometimes can be cached or collected through OSINT, Google Dorks, or Shodan.
The next phase is discovery and mapping out the network, which involves detecting service over ports, and outdated modules and collecting network IP range; probing and scanning using tools and techniques to build intelligence against target sites.
It helps in this stage to build plan attacks and watch for system behaviors against servers or misconfigured defenses.
In addition, security researchers could use open-source tools and commercial ones such as BurpSuite Pro or Nmap for port probing and network.
Another known tool is metasploit which contains known vulnerabilities and exploits against OS/ servers or web applications and KaliLinux, which is considered the Swiss knife of all hacker tools.
With the collected information, hands-on attacks take place and deliver exploits against target systems and cause the system to disclose unintended information.
The results normally are shared in the form of a report with head departments and their technical engineers to better understand the impact and ways to provide protection against threat agents.
Pentesting shows that the organization has evaluated its security posture and defenses. Penetration testing requires an understanding of common vulnerabilities and how network packet traffic and protocols work.
It requires creative, analytical, and critical thinking skills to spot vulnerabilities and provide proof of concept.
Writing automated scripts is in high demand because this skill is needed for tweaking, customizing, or outright developing your own tools.
Creating customized tools is an important part of automating the daily routine of today’s information security professionals. Creating scripts allows security professionals to achieve more value in less time.
Organizations that are serious about security have a need for skilled tool builders. There is a huge demand for people who can understand a security problem and then rapidly develop a prototype code to attack or defend against it and fully weaponized, for example, writing a backdoor script that uses Exception Handling, Sockets, Process execution, and encryption provides an initial foothold in a target environment.
The backdoor will include features such as a port scanner to find an open outbound port, techniques for evading antivirus software and network monitoring, and the ability to embed payload from tools such as Metasploit or Scapy for writing network traffic packets.
There are many online resources to learn and it requires discipline and commitment to become proficient:
Pentesting Labs is an online course at your own pace designed to help improve security pen-testing skills; it has various levels of labs and domains of attacks such as SQL injection (SQLi), XSS, and escalation of privileges.
Hack The Box is a digital lab designed to immerse yourself in real-world environments to perform pen-testing. If you completed 48 labs, you’re ready for the OSCP certification exam. One of the best online guides for passing this certificate can be found here.
Offensive Security provides an online self-paced course designed to become proficient in ethical hacking. The course requires some fundamental skills such as OWASP’s top ten of web vulnerabilities and attacks. Linux and Windows terminal commands.
Bug bounty programs are a platform designed for organizations that are interested in evaluating their security posture. Ethical hackers/pen-testers and security researchers access the bounty-paying organization’s target sites under a safe harbor agreement to perform advanced testing.
After looking for weaknesses, the security researcher or ethical hack presents a proof of concept report of the found vulnerability so the organization can reproduce the attack and retest it after applying the patch, and then receives a bounty which could range from $100s to over $20,000 depending on the severity of the vulnerability.
Refers to security controls dedicated to withstand or deter aggression or attack to avoid risk, danger, or cybercrime threats like espionage, sabotage, or attack. It can be a reactive or proactive security measure to minimize the likelihood of possible loss of the data.
Here is a good online course that offers defensive security online classes from an organization fittingly called Defensive Security.
There are several phases of defensive security, and so there are also several directions that online training can take:
Detection and monitoring
Detection and monitoring defensive security is just like it sounds. The practice refers to a systematic approach for identifying and tracking threats such as malware beaconing outbound and spear phishing attack mechanisms.
This process involves tracking the activities of users and hackers second-by-second on the system you are analyzing through in-depth timeline and super-timeline analysis and how the attacker acquires legitimate credentials — including domain administrator rights — even in a locked-down environment.
There are tools and techniques that involve analysis and detection such as Snort, Zeek/Bro, and other open-source tools such as tcpdump and Wireshark.
The data are ingested for enrichment to provide data dashboards and visualization to capture metrics for reporting purposes such as using collected data to perform effective remediation across the entire enterprise.
There are many courses and online materials you can start with to learn security detection and monitoring techniques including:
Cybrary: Cybrary is an online platform that provides a number of free online training courses suitable for entry-level cybersecurity all the way through seasoned professionals with courses, virtual labs, and practice tests all in one spot and taught at just the right time, you can stay focused on your career development.
The organization also provides mentoring programs to connect with dedicated mentors for career tips and advice.
SANS: SANS provides intensive, immersion training designed to help you and your staff master the practical steps necessary for defending systems and networks against the most dangerous threats — the ones being actively exploited.
The courses are full of important and immediately useful techniques that you can put to work as soon as you return to your job. They were developed through a consensus process involving hundreds of administrators, security managers, and information security professionals, and address both security fundamentals and awareness, and the in-depth technical aspects of the most crucial areas of IT security.
The environment is to serve the constant improvement of competencies in the field of threat hunting (threat hunting) and learning about current trends of offensive actions (red teaming) vs direct detection (blue teaming).
Incident response and threat hunting
Incident response training helps security professionals do a deeper analysis to understand the meaning behind security-related incidents. An incident is any event that has a negative impact on the confidentiality, integrity, or availability of an organization’s assets.
Incident response (IR) is a reactive measure and it’s made of several steps. The first step of the incident response (IR) is vulnerability detection using tools such as Qualys, which is a platform designed to run a proactive vulnerability assessment for endpoints and web applications. Qualys offers free training and certifications that teach individuals steps to run the tools and features and generate reports.
Another good tool is Rapid7-Nexpose, which provides a vulnerability assessment tool called Nexpose. Rapid7 offers hands-on training sessions This two-day interactive class covers advanced topics for extending and analyzing the wealth of data the product provides.
The next step is the response, which involves evaluating the nature of the vulnerability and determining the severity level based on risk appetite. The next step is mitigation, which involves the reduction of the vulnerability by applying compensating controls and reducing the risk to an acceptable level.
In some cases, responders take steps to mitigate the incident, but without letting the attacker know that the attack has been detected. This allows security personnel to monitor the attacker’s activities and determine the scope of the attack.
After that step, reporting and recovery take place to submit the fact-finding and report to the management. The next step is remediation, which involves an attempt to identify what allowed it to occur, and then implement methods to prevent it from happening again.
This includes performing a root cause analysis. The last step is lessons learned to improve detection methods or help prevent repeated incidents.
SANS offers GCIH certification for individuals who are interested in learning incident response and handling. The course provides information about cyber threat hunting, which is a proactive measure, and digs deep into finding malicious actors in a target environment that have slipped past your initial endpoint security defenses.
An attacker can remain stealthily in a network for months as they quietly collect data, look for confidential material, or obtain login credentials that will allow them to move laterally across the environment.
The process of cyber threat hunting involves three steps: a trigger, an investigation, and a resolution. SANS also offers threat-hunting training.
Security compliance and risk assessment
Security compliance and risk assessment is a set of procedures that helps to identify, assess, and implement the risks in your organization to make sure that controls are in place.
Risk assessment can be found in government, financial services, healthcare, and many industries that handle sensitive data and perform proactive measures to evaluate their defenses and security coverage.
This assessment gives you the whole risks that exist in your organization and provides you with how critical each issue is.
Knowing where to start when enhancing your security allows you to maximize your IT budget and resources, saving you money and time. SANS offers A Practical Introduction to Cyber Security Risk Management and a list of security compliance and policies
If you have ever tried to adjust your privacy settings in a mobile/web app or a social media site or tried to figure out how to exercise privacy choices on a website, chances are you encountered a privacy interface.
Privacy security sets forth standards for the collection, processing, transfer, deletion, and other use of personal data, including in the context of organization operations, clinical research, use and deployment of facial recognition and other sensors, web and mobile device tracking, artificial intelligence, machine learning, big data, and analytics, among others.
Privacy standards are intended to reflect best practices. As privacy laws and principles evolve over time, these standards will be revised and updated accordingly. In time, these standards are intended to become requirements codified.
Some of the standards are about data anonymization, need to know, giving the right to remove user’s data, or the choice to enable or disable cookies.
Cloud security refers to the technologies, policies, controls, and services that protect cloud data, applications, and infrastructure from threats. AWS, GCP, and MS Azure are top cloud services used by many businesses.
Cloud computing has become an attractive target for hackers as they find misconfigurations, poor security defenses, and a lack of protecting Key Secrets (KS), applying appropriate Identity Access Management (IAM) policies and trigger points for abnormal behaviors. There are many cloud security training that provide fundamentals for securing cloud-based solutions:
Cloud Academy: This service is a platform designed to help individuals who are interested in obtaining certifications and hands-on labs on the following cloud services including Amazon Web Services, Google Cloud, Microsoft Azure, and many other cloud providers in the market.
The courses cover security, identity and access Management (IAM), cloud administration, and architecture of cloud services.
Udemy for Cloud Azure and AWS: This course covers relevant topics securing computing infrastructure on Amazon Web Services and Microsoft Azure. The course also provides info about how to integrate security services with cloud-based applications.
SANS Cloud Security provides many courses including cloud security courses that involve AWS, Google Cloud, and Microsoft Azure. SANS training will equip you with the latest in cloud-focused penetration testing techniques and teach you how to assess cloud environments such as cloud-based microservices, in-memory data stores, serverless functions, Kubernetes meshes, and containers, as well as identifying and testing in cloud-first and cloud-native applications.
You will also learn specific tactics for penetration testing in Azure and AWS, particularly important given that Amazon Web Services and Microsoft account for more than half of the market. It’s one thing to assess and secure a data center, but it takes a specialized skill set to truly assess and report on the risk that an organization faces if its cloud services are left insecure.
You also learn how to implement over 20 DevSecOps Security Controls for building, testing, deploying, and monitoring cloud infrastructure and services. Immersive hands-on labs ensure students not only understand the theory but how to configure and implement each security control.
