Computer Network Security

RSA is a data-encryption technology utilizing prime factorization. Its name is derived from the developers who created it: Rivest, Shamir and Adelman.

They use the attack called shoulder surfing, which is looking over someone's shoulder to get personal information.

First the advantages. A secure network has much less likelihood of unauthorized access which could result in corrupted data, stolen data, or malicious damage to a database. Some form of encryption is usually used to make data unreadable even if it is stolen. The chief disadvantage is slowdown of the system. Encrypted data must be un-encrypted, users have to be verified, some IP addresses have to be blocked, etc.

The company McAfee is the largest company that produces security technology. There are also several other companies that offer similar services, such as Skybox Security, Inc; eEye digital security; Symantec Corporation and Tenable Network Security.

There are many activities and tasks a person could focus on. If in school a student would need to focus on their classes and assignments first and the. Any clubs or activities such as sports, band, or color guard. If a person is not in school they would need to focus on work and twit family. Some activities could be family game night, knitting or crocheting, and painting.

While the term security arises the cryptography or cryptology always comes at the top of the list on the topic of security of any system, device and whatever else. The technique of transforming and storing information or in the ease of communication between two parties cryptography helps to connect, store and transform with security.

You con not be totally secure on any network, secured or unsecured. There is always someone out there that would "love to show us what we don't know about computers". Not my words, someone else's that I used to work with. However, you can be relatively secure. You can use SSL. You can use a secured VPN. You can ... It hard to quantify security. Is it 99%? Is it 99.997%? It comes down to safe practices - Updated OS - Current Antivirus - not doing unsafe things.

Email hackers are generally tracked by Cyber crime police. They can track the IP address of the hacker. With the IP address, they can track the location of person.

One wastes our air and other resources. The other polutes the air and uses coal.

SUBNET: subnet is a group of networks having same network id. subnet increase the number of hosts with same network address, as result it reduces the wastage of addresses.

In subnetting bits of hostId will be captured by networdId.

SUPERNET:

supernet makes all the hosts with in a range of network address belong to a same group. This reduces the entries in the network address table.

Supernetting combines the octets of the address.

IP stands for Internet Protocol, and is the means of 2 computers sending information to one another. The IP address for a Linksys router is usually 192.168.11, and may be the IP address for other manufacturers as well.

There are two main types of software that offer data security for the network of home users, including Personal Firewalls & Encryption. Personal Firewalls protect you from network intrusions like viruses, and Encrytion protects your sensitive data while you're online.

In general, the MAC address is tied to a specific piece of hardware and does not change. It is possible, however, under certain circumstances to change the MAC address.

MAC addresses are most often assigned by the manufacturer of a network interface card (NIC) and are stored in its hardware, the card's read-only memory, or some other firmware mechanism. If assigned by the manufacturer, a MAC address usually encodes the manufacturer's registered identification number and may be referred to as the burned-in address. It may also be known as an Ethernet hardware address (EHA), hardware address or physical address.

Although intended to be a permanent and globally unique identification, it is possible to change the MAC address on most modern hardware. Changing MAC addresses is necessary in network virtualization. In this case, the MAC address of the actual NIC is hidden from the network and the network only sees the MAC assigned to the virtual NIC - which can be configured, with some finesse, to be dynamic. It can also be used in the process of exploiting security vulnerabilities. This is called MAC spoofing.

In very simple words, A leased line is a rent paying line; as the name suggests.

As it is very difficult to connect two different point in far flange areas, a customer uses a line that is provided by some network provider and pays accordingly.You can take it as connecting some of your database in two different cities.

Hope, you understand me :)

A packet capture (or sniffer) program sees packets coming into and out of the NIC (network interface card). It saves it for later analysis and use. These capture programs can be used to analyze traffic, look for problems, or be used for looking at data coming across the network.
