Cyber security is the protection of computer system and network operations from any kind of theft, malpractice, damage, misuse or misdirection of services that can hamper user functioning and services offered. These threats in the cyber world can lead you to lose sensitive data (for e.g., intellectual property, financial data, personal information or data of strategic importance) via networks and other devices as well.
In this fast paced world with hyper connectivity through electronic media and internet, the need to secure our cyber space and footprints has been noted by world governments, businesses, finance, and healthcare organizations as they collect, process, and store unprecedented amounts of data on computers and other devices. Most of this is sensitive, whether and can be misused by unauthorized access or disclosure. Organizations send sensitive data to networks and other devices as part of their business and hence come the dire need for Cyber security which basically is a continuous attempt to protect the information and the systems that process or store it.
Team IHA has extensively researched and toiled to create a subdivision which exclusively works with cyber security and all its components. We have the most updated and skilled IT professionals who excel in investigation, protection, recovery and other requirements to secure your cyber space.
Let’s have a sneak peek into what all Cyber Security entails and Team IHA’s services to ensure a safe cyber experience to its users.
Network security is a broad term that includes various technologies, devices, and processes. Simply put, this is a set of rules and configurations designed to protect the integrity, confidentiality, and accessibility of computer networks and data using software and hardware technologies. All businesses, regardless of size, industry, or infrastructure- need some degree of network security solution to protect them from the growing cyber insecurity.
Today's network architecture is very complex and ever evolving. This increases the risk of threat and the probability of exploitation of weak links & vulnerabilities. These vulnerabilities can exist in a large number of domains, including devices, data, applications, users, and locations which the hackers are always looking for. For the same reason, there are many cyber security management tools and applications today that address individual threats and exploits as well as regulatory non-compliance when a few minutes of downtime can cause widespread disruption and significant damage to an organization and its reputation.
Application security is an application-level security measure designed to prevent the data and code in your application from being stolen or hijacked. This includes security considerations that arise during application development and design, as well as systems and approaches to protect your app after it is deployed. Application security can include hardware, software, and procedures that identify or mitigate security vulnerabilities. A router that prevents someone from seeing your computer's IP address from the Internet is a form of security for your hardware application. However, application-level security measures are usually integrated into the software. An application firewall that strictly defines allowed and prohibited activities. Procedures can include application security routines that include protocols such as regular testing.
Information security is designed and implemented to protect sensitive information, personal information, confidential information or data in print, electronic or other forms from unauthorized access, use, misuse, disclosure, destruction, tampering or interference. Information can be something like data, social media profiles, cell phone data, biometrics, and so on. Therefore, information security includes numerous research areas such as cryptography, mobile computing, cyber forensics, and online social media, etc. Information Security programs are focused around 3 objectives, commonly known as CIA – Confidentiality, Integrity, and Availability.
Operational security focuses on risk management processes to identify potential threats and vulnerabilities before they are exploited and cause problems for organizations. Businesses can build and implement a comprehensive and robust Operational security program by following these best practices:
- Change management processes: Organizations must implement specific change management processes that their employees can follow in case network changes are performed. These changes must be controlled and logged so that organizations can appropriately audit and monitor the amendments.
- Restrict device access: Organizations must restrict access to their networks to only devices that absolutely require it. Military agencies and other government organizations deploy a "need to know" basis around their networks, and this theory also must be applied to corporate networks. Network device authentication should be used as a common rule of thumb when it comes to access and information sharing.
- Deploy least privilege access: Employees need to be assigned the minimum level of access to data, networks, and resources that they require to do their jobs successfully. This means deploying the principle of least privilege, which ensures that any program, process, or user only has the bare minimum privilege required to perform its function. This is crucial to organizations ensuring better security levels, preventing insider threats, minimizing the attack surface, limiting the risk of malware, and improving their audit and compliance readiness.
- Implement dual control: Users responsible for managing their networks should not be made in charge of security. Organizations need to ensure that the teams or individuals responsible for maintaining the corporate network are isolated from the teams or individuals who set security policies.
- Use automation: People are often the weakest link in an organization's security process. Man-made errors can lead to errors, misuse of data, overlooked or forgotten important details, and bypass of critical processes.
- Disaster Planning: An important part of security defense is the implementation of disaster planning and a solid incident response plan. Even the most robust OPSEC security needs to be backed by plans to identify potential risks and outline how organizations respond to cyber attacks and mitigate potential damage.
End-user education is building awareness among employees by equipping them with the necessary tools and skills required to protect themselves and the company data from loss or attack. Periodic end-user education and reviews are imperative to highlight the organizational weaknesses, system and security vulnerabilities to the employees. In today’s complicated threat landscape, cyber attackers use highly sophisticated methods of targeting your employees as entry points into private company systems. The more employees are aware of cyber threats, the better they can spot the early signs of an attack and keep themselves protected. Increasing knowledge with security awareness training is one of the most effective ways to reduce cyber security risk and build security-aware culture.
Cyber forensics simply means looking up, collecting, and analyzing information from computer devices. This information can be converted into hardware evidence that can be presented to court in connection with the crime in question. A very important aspect of the investigation is to make a digital copy of the computer's memory cells and analyze it further to prevent accidental damage to the device itself throughout the process. The aim is to only find malware in the software part of the device and leave the actual component of it on one side. While studying the entry and exit points of the device’s storage, one can easily and efficiently learn about the individuals who accessed the device and the circumstances under which the logs were made which in turn gives a crystal-clear picture of what happened and at what date and time. Cyber forensics is an unavoidable force that is extremely significant in today’s ever-changing, evolving, and technologically transforming world.
