Which of the following is an objective of network security

Correct Answer : Option (B) : Spyware Explanation : Spyware is professional malicious spying software that is hard to detect by anti-malware or anti-virus programs because they are programmed in such a skillful way. These types of software keep on collecting personal information, surfing habits, surfing history as well as credit card details. Show Answer

The first two pillars are ‘people’ and ‘process’, The last pillar is ‘data and information’. Data and information protection is the most technical and tangible of the three pillars. The data we gather comes from multiple sources, such as information technology (IT), operational technology (OT), personal data and operational data. It must be properly managed and p...

Network security is a broad term that covers a multitude of technologies, devices and processes. In its simplest term, it is a set of rules and configurations designed to protect the integrity, confidentiality and accessibility of computer networks and data using both software and hardware technologies. Every organization, regardless of size, industry or infrastructure, requires a degree of network security solutions in place to protect it from the ever-growing landscape of cyber threats in the wild today. Today's network architecture is complex and is faced with a threat environment that is always changing and attackers that are always trying to find and exploit vulnerabilities. These vulnerabilities can exist in a broad number of areas, including devices, data, applications, users and locations. For this reason, there are many network security management tools and applications in use today that address individual threats and exploits and also regulatory non-compliance. When just a few minutes of downtime can cause widespread disruption and massive damage to an organization's bottom line and reputation, it is essential that these protection measures are in place. There are many layers to consider when addressing network security across an organization. Attacks can happen at any layer in the network security layers model, so your network security hardware, software and policies must be designed to address each area. Network security typically consists of three different co...

Pre-Requisite: Network Security refers to the measures taken by any enterprise or organization to secure its computer network and data using both hardware and software systems. This aims at securing the confidentiality and accessibility of the data and network. Every company or organization that handles a large amount of data, has a degree of solutions against many The most basic example of Network Security is password protection which the user of the network oneself chooses. In recent times, Network Security has become the central topic of • Users • Locations • Data • Devices • Applications Benefits of Network Security Network Security has several benefits, some of which are mentioned below: • Network Security helps in protecting clients’ information and data which ensures reliable access and helps in protecting the data from cyber threats. • Network Security protects the organization from heavy losses that may have occurred from data loss or any security incident. • It overall protects the reputation of the organization as it protects the data and confidential items. Workingon Network Security The basic principle of network security is protecting huge stored data and networks in layers that ensure the bedding of rules and regulations that have to be acknowledged before performing any activity on the data. These levels are: • Physical Network Security • Technical Network Security • Administrative Network Security These are explained below: 1. Physical Network Security: Th...

Explanation: There are many cipher methods developed for message encryptions. In transposition ciphers, no letters are replaced; they are simply rearranged. An example of this type of cipher is known as the rail fence cipher. In this transposition, the words are spelled out as if they were a rail fence, meaning some are in front and some in back across several parallel lines. 2. What are two objectives of ensuring data integrity? (Choose two.) • Access to the data is authenticated. • Data is unaltered during transit. • Data is available all the time. • Data is encrypted while in transit and when stored on disks. • Data is not changed by unauthorized entities. Explanation: The objectives for data integrity include data not being altered during transit and not being changed by unauthorized entities. Authentication and encryption are methods to ensure confidentiality. Data being available all the time is the goal of availability. 3. A network security specialist is tasked to implement a security measure that monitors the status of critical files in the data center and sends an immediate alert if any file is modified. Which aspect of secure communications is addressed by this security measure? • data integrity • data confidentiality • origin authentication • nonrepudiation Explanation: Secure communications consists of four elements: • Data confidentiality – guarantees that only authorized users can read the message • Data integrity – guarantees that the message was not altere...

Network security covers many technologies, devices, and processes. It refers to a set of rules and configurations designed to protect the integrity, confidentiality, and accessibility of computer networks and data. Sound network security controls are recommended for organizations to reduce the risk of an attack or data breach. These measures also enable the safe operation of IT systems. Network security consists of hardware and software technologies and are ideally composed of layers that include applications, antivirus, access management, servers, firewalls, physical access, and policies. Every digital business, regardless of size, industry, or infrastructure, requires a degree of network security solutions in place. This goal can only be achieved with the help of well-trained and certified professionals who can secure and protect their networks from the ever-growing landscape of cyber threats in the wild today. The importance of network security in the modern business atmosphere has increased after a major portion of the workforce went remote due to COVID-19. Today, the office system is distributed in one huge network across multiple locations. A centralized system to protect network devices from being breached doesn’t exist in the same capacity. This scenario leaves more vulnerable points that hackers can take advantage of. In March 2020, Marriott International suffered a major data breach in which the information of 5.2 million guests was accessed using the login crede...

Network Infrastructure Security, typically applied to enterprise IT environments, is a process of protecting the underlying networking infrastructure by installing preventative measures to deny unauthorized access, modification, deletion, and theft of resources and data. These security measures can include access control, Network Infrastructure Security requires a holistic approach to ongoing processes and practices to ensure that the underlying infrastructure remains protected. The Cybersecurity and Infrastructure Security Agency (CISA) recommends considering several approaches when addressing what methods to implement. • Segment and segregate networks and functions - Particular attention should be paid to the overall infrastructure layout. Proper segmentation and segregation is an effective security mechanisms to limit potential intruder exploits from propagating into other parts of the internal network. Using hardware such as routers can separate networks creating boundaries that filter broadcast traffic. These • Limit unnecessary lateral communications - Not to be overlooked is the peer-to-peer communications within a network. Unfiltered communication between peers could allow intruders to move about freely from computer to computer. This affords attackers the opportunity to establish persistence in the target network by embedding backdoors or installing applications. • Harden network devices - Hardening network devices is a primary way to enhance network infrastructur...
