Things You Need To Know About Information Security Cyber Security, And Network Security

1. Things You Need To Know About Information Security Cyber Security, And Network Security Information Security Information security is the methodologies and processes that are specially designed and implemented to protect the electronic, print, or any other form of sensitive data or information from unauthorized access, disclosure, use, misuse, disruption, or modification. Simply put, information security is made to safeguard an information system – which is any point of data storage, even those outside cyberspace. Principals of Information Security The principles of information security are summed up in what is known as the CIA triad: confidentiality, integrity, and availability. 1. Confidentiality: This is one of the most important elements that come into mind whenever you think of information security. All data is confidential when only accessed by those authorized to do so. To ensure maximum confidentiality, you must identify those who want to access your data without your consent and block their attempts. Some of the techniques designed to ensure confidentiality include passwords, two-factor authentication, and encryption. 2. Integrity: This is another principle of information security that means maintaining data in its correct and original state and protecting it from being improperly modified either maliciously or by accident. A majority of techniques designed to ensure confidentiality are also meant to protect data integrity since hackers can’t alter data if they can’t access it. However, there is a multitude of tools that can help verify data integrity, such as version control software and backup tools. 3. Availability: Availability is basically a mirror image of confidentiality. While you need to ensure unauthorized parties don’t access your data, you also need to ensure that it is available to those with permissions. Ensuring availability means matching computer resources and the network to the volume of data access you want and implement a reliable backup policy in case an unexpected breach occurs. Network Security By definition, network security is the process of taking software and physical preventive measure to protect underlying networking infrastructure from unauthorized access, malfunction, misuse, destruction, improper disclosure, or modification, hence creating a secure platform for computers, programs, and users to perform critical functions in a secure environment. Network security is the practice of protecting and preventing unauthorized intrusion into corporate networks. It focuses on how individual devices within an organization interact. It is implemented by the tools and tasks used by a computer user to prevent unauthorized programs or people from

In essence, hackers and other parties with malicious intent cannot hack your computer if they can’t get to it over the network you are connected to. Network Security Basics Network security consists of: ·Protection: Users need to configure their systems and networks as correctly as possible to prevent breaches to the network. ·Detection: Networks that are well protected should allow users to identify when the configuration has changed or when network traffic indicates a problem. ·Reaction: After identifying problems swiftly, users should be able to respond to them swiftly and return to a safe state as soon as possible. Top network security methods There are many network security methods. They include: ·Access control: This is blocking unauthorized users and devices from accessing the network. Even users who are allowed in the network are only able to work with a limited set of resources which they are authorized to access. ·Application security: insecure apps are often the vectors in which attackers access a network. Users should employ hardware, software, and a myriad of security processes that lock such apps. ·Data loss prevention: The weakest security links within an organization are human beings. You, therefore, need to implement tools, technologies, and processes that ensure employees don’t inadvertently or deliberately send sensitive data outside the network. ·Firewalls: Firewalls are arguably the granddaddy of the network security space. They often follow the rules defined by the user to deny or permit traffic at the border between the internet and the network, hence establishing a barrier between trusted zones and the Wild West outside. ·Network Segmentation: This is software-driven segmentation that puts network traffic into different classifications and makes it easier for organizations to enforce security policies. Cybersecurity Cybersecurity is the act of protecting networks, systems, and programs from digital attacks. These attacks are often aimed at changing, accessing, accessing, or destroying sensiti8ve data,

Cybersecurity is divided into: Cyber Security Disaster Recovery and Business continuity Applicati on Security Informati on Security Operation al Security End-User education · Application security: This focuses on keeping devices and software free from threats. Application security should be implemented when programs are being developed, or devices are deployed to enhance successful security. Network security: This is the practice of securing computer networks from unauthorized third parties, whether opportunistic malware or targeted attackers. ·Information security: It is designed to protect data privacy and integrity, both in transit and in storage. ·Operational security: It includes the processes and decisions for protecting and handling data security. ·Disaster recovery and business continuity: It defines how organizations should respond to cybersecurity incidents or any other event that causes data loss. Business continuity is the plan an entity falls back on while attempting to operate without compromised resources. ·End-user education: It focuses on educating people on basic and advanced cybersecurity practices such as deleting spam emails, using strong passwords and two-factor authentication, and other essential security insights.

Information Security Vs. Network Security Since information technology has turned out to be a buzzword that means computers and related networks, it is easy to use cybersecurity, network security, and information security interchangeably. Cybersecurity is basically the broader practice of defending IT assets from unexpected attacks, while information security and network security are disciplines under the cybersecurity umbrella. When you choose a career in cybersecurity, you can easily become an expert in all these aspects.
