Scripting is a language which enables users to write scripts that manipulate text or images, similar to how programmers use syntax to write code. Most modern operating systems have scripting languages built-in, such as Apple’s Automator. You can also do scripting using specialized applications such as Adobe Photoshop. Scripting languages are  designing for specific tasks such as file management, data conversion, web authoring, database administration, or computer programming. Scripting languages vary greatly based on their purpose, features, and popularity. In addition, some languages may offer special capabilities not found in others.

Controls and frameworks

Security controls are designed to protect assets and/or information from unauthorized access, use, disclosure, modification, disruption, etc. There are two types of security control: physical and non-physical. Physical security controls are mainly concerned about preventing the unauthorized entry to a facility (e.g., doors, gates). Non-physical security controls are those related to protecting data and systems (e.g., firewalls, encryption, etc.). A combination of both physical and non-physical controls may be implemented to provide additional security.

A framework is a set of standards, guidelines, best practices, techniques, rules, procedures, standards, etc., that provide a starting point for people who want to learn more. Frameworks help individuals understand what they need to do before implementing their own plan.

Intrusion detection

Intrusion Detection systems (IDS) are devices designed to identify suspicious activity occurring within a computer network. These types of systems may use packet sniffing, protocol analysis, behavioral analysis, signature matching, anomaly detection, or any combination of these technologies. IDS systems are utilizing to protect networks from attackers who use techniques such as denial-of-service attacks, distribute denial-of-service attack, man-in-the-middle attacks, Trojan horse viruses, unauthorize accesses, data theft, etc. A basic IDS system consists of 2 parts, hardware and software. The hardware portion contains sensors that detect traffic on the network. This information is then sent to a central server where it is processed and analyze.

Software is installing on the server to analyze the detect information. When anomalies are detecting, alerts can be generates to notify administrators regarding the intrusion. If requires, security controls can be implement to prevent future occurrences. Types of IDS include Network Watcher, Host Intrusion Detection System (HIDS), Application Layer Intrusion Detection System(ALIDS), Web Server Intrusion Detection System and Firewall Intrusion Detection Systems (FWIDS). There are many different vendors that offer IDS solutions.

The following are some examples of vendors offering IDS products:

Network security control

Network security control (NSC) is a term commonly used in the information technology industry. NSC refers to the set of measures put in place to safeguard a network by preventing unauthorized access and usage of the network. In addition, it seeks to ensure secure data flow between the users/end-user equipment and the network infrastructure.

Incident response

Incident Response, commonly abbreviated IR, means identifying and responding to incidents (problems) that might occur in a computer systems. These situations may range from problems caused by viruses, spyware, trojans, worms, denial-of-service attacks, hacking attempts, etc. to problems associated with malware infections which make data, files or system changes without permission. IR also includes tasks such as detecting and preventing, isolating, containing, and remediating malicious software. In addition, incident responders need to ensure that the affected computer systems are maintained until they are returned to their normal operational state.

What is cloud?

Cloud computing refers to providing applications over the web (the cloud). In cloud computing, consumers access their data via the internet and pay only for the amount of storage they use, rather than paying for fixed hard drives or servers.

What is DevOps?

DevOps is short for “Development and Operations”. The term  first introduce at Facebook in 2010 where DevOps teams are set up to work together to develop code faster, build more efficiently, release code more often, and also make sure that operations team have everything working smoothly.

What is Dev Sec Ops?

Dev Sec Ops aims to blend the best practices and technologies from both DevOps and Security fields into one cohesive set of processes and tools. The goal of Dev Sec Ops is to create a strong foundation of security-mindedness across all engineering disciplines while still enabling innovation.

What is Cloud Security and Compliance?

Cloud security and compliance involves protecting information assets stored online instead of keeping them offline. There are several different types of threats to consider including malware, malicious insiders, phishing, social engineering, hacking, and denial-of service attacks. These threats are not only threats to users but also threats to businesses as well. According to the 2017 NSS Labs report, 97% of enterprises experience some type of breach each year. A good Dev Sec Ops strategy should begin by understanding the business goals and objectives, then identifying potential risks, and finally developing mitigation plans.

 What is Cloud Security Architecture?

A cloud security architecture is a framework that helps companies identify cloud services, understand how they interact with other services, and determine if those interactions are safe. This includes finding out who owns the service, whether it’s secure, and when it goes down or changes ownership.

What is a Cybersecurity Incident?

A cybersecurity incident is any event that exposes confidential data or disrupts normal operations. Incidents can occur due to human error, malicious actions, technical vulnerabilities, internal sabotage, or natural disasters.

 Physical Security

Physical security includes everything about your facility from doors and windows to locks and alarms. All these things should work together to keep people out while allowing access only to those who have permission. If someone isn’t supposing to enter your facility, then they shouldn’t be able to get in either. A physical security plan is essential to keeping your business safe and secure.

Software Security

Software security includes firewalls, anti-virus programs, and security appliances to protect your PC’s from malware. Also, regular updates are recommends.

Network Security

Network security involves protecting information on the network from unauthorized users and preventing data loss. This means having firewall rules set up correctly to block any malicious activity, and using encryption methods to ensure confidential information remains private.

Infrastructure Security

Infrastructure security covers how the hardware works and what components need to be add to make sure that it will continue to function properly. Hardware security includes firewalls and servers, among other devices.

Data Protection

It ensures that sensitive records remain confidential and are not accessible to unauthorized individuals. Data protection includes firewalls and server configurations to prevent hackers from accessing your system.

Compliance Standards

Compliance standards involve knowing what laws apply to your company and complying with them. These regulations may include government agencies or industry associations that require companies to meet certain requirements. Knowing what types of products are allowing is critical to ensuring compliance.

Asset Management

Asset management is similar to data protection and refers to tracking property and equipment to determine if they are working properly. In addition to inventory control, asset management requires proper documentation and recording.
