Security Management for networks is different for all type of situations. A small home or an office would only need basic security while high businesses will need high maintenance and advanced software and hardware to avoid malicious attacks from hacking and spamming.Small HomesA basic firewall.For Windows users, basic Anti-virus software such as McAfee, Norton AntiVirus or AVG Antivirus.An anti-spyware program including Windows Defender or Spybot would also be a best concept. There are some types of antivirus or antispyware programs out there to be considered.When utilizing a wireless connection, use a robust password. It can also use the strongest security ... Read More

A trusted network addresses the following security issues such as partially or completely which are as follows −Firewall Configuration Errors (Partial) − A TPCN divides the group of firewall rules into smaller rule sets related to each access control group or role. These rule sets are sent by the AAA server to the NADs for administration upon completion of the authentication process.As per the several configuration errors reduces logarithmically as the rule set complexity decreases. Because a TPCN has smaller rule sets, the capability for firewall configuration errors is properly lower. Furthermore, access rules in a TPCN are defined based ... Read More

A trusted network architecture facilitate information about the hardware and software states of devices in admission and access control decisions. When a device first “joins” the network, its hardware and software are tested; depends on these checks, the appropriate access control rules are used dynamically to the user, device and traffic.In a trusted network, a user device determined to join the network connects its request to the NAD. The NAD creates the client device’s identity using EAP over the 802.1x protocol and sends the results to the AAA server utilizing the RADIUS protocol. The AAA server fix a document of ... Read More

Trusted networks are represented as the networks within your security boundary, and are generally the networks it is trying to defend. Computers on the trusted network can certainly access such departmental services as NFS (home and project disks), NIS (distributed account and multiple data), printers, software packages, etc.Access to this network is secured to machines supervised by the Lab Staff, so as to secure sensitive information and uphold the accessibility of departmental resources. A recent list of machines on the trusted network can be situated here.A trusted network (TN) architecture uses current standards, protocols and hardware devices to implement “trust.” ... Read More

Network security management is the study of managing firewalls and policies to secure the network and is best completed through a centralized solution. Network security management includes several rules and processes adopted by network administrators to provide that unauthorized users do not obtain access.Security contains a host of policies that limit access. The process creates the network secure and protects and manages network services. The essential form of network security supports users the ability to distribute a password or ID to individuals to support access.Network administrators control and should decide the users who can access network data. These users are ... Read More

Network security is a group of technologies that secure the usability and integrity of a company’s infrastructure by avoiding the entry or proliferation within a network of a broad variety of potential threats.A network security architecture is composed of tools that secure the network itself and the software that run over it. Effective network security methods employ several lines of defence that are scalable and automated. Each defensive layer apply a group of security policies decided by the administrator.Network security works with several layers of protection at the edge and in between the network. Some security layers implement some strategies ... Read More

MAN stands for the Metropolitan Area Network. It is represented as the computer network that joins the metropolitan areas. MAN works either through wires or modem. Telephone company network is an instance of MAN as they support highspeed DSL line to the consumers.The features of MAN is that it is the interconnection between several connection in a metropolitan area. Point-to-point connections are used in MAN. The network size of MAN ranges from 5-50 Kms.MANs are completely efficient and can support fast communication via high-speed carriers, including fiber optic cables. The rise of wireless and successive networking technologies, though, means a ... Read More

WAN stands for Wide Area Network. A Wide Area Network is a network that extends over a large geographical area including states or countries. A Wide Area Network supports a large geographical area. Suppose if the branch of the office is in a multiple city then it can link with them through WAN. The internet supports a leased line through which it can connect with multiple branch.WANs are set of interconnected local area networks (LANs), which are defined to a physical areas. WANs are created by telecommunications service providers, who then lease these capabilities to multinational or otherwise high enterprises ... Read More

LAN stands for Local Area Network. A Local Area Network (LAN) is a set of computers and associated devices that send a common communications line or wireless connection and share the resources of an individual processor or server inside a small geographic area generally within an office building.Generally, the server has applications and data storage that are shared in common by several computer users. A local area network can serve as few as two or three users (for instance, in a home network) or as some thousands of users.LANs have become commonplace in several organizations for supporting telecommunications network capabilities ...

There are three types of Networks in Information Security which are as follows −Local Area Network (LAN) − Local area network is a computer network that works in a small area, i.e., it connects computers in a small geographical location like inside an office, company, school, or any other organization. Therefore, it exists within a specific location, such as home network, office network, school network, etc.A local area network can be a wired or wireless network or a set of both. The devices in a LAN are usually linked using an Ethernet cable, which provides an interface to connect multiple ... Read More
