How secure is your data? How safe is your information?
Cryptography and Network Security Behrouz Solution
Network Security Behrouz Solution is a network security solution that provides VPN, firewall, and intrusion detection. A virtual private network (VPN) is a private network that uses a public telecommunication infrastructure. This is such as the Internet to provide remote offices or individual users with secure access to their organization’s network.
A VPN allows a remote user or site to send and receive data across shared or public networks as if it were on a private network. Data traffic can be encrypted to ensure privacy. VPNs may be used by employees working remotely, and also allow secure access to a corporate intranet.
An Intrusion Detection System (IDS) is a system designed to detect unauthorized access attempts or malicious activity. IDSs are placed at locations in a network to detect malicious activity. An IDS can detect attacks against the network.
However, it does not prevent them from being successful unless it is also an Intrusion Prevention System (IPS). An Intrusion Prevention System (IPS) differs from an IDS in that it actively protects the system from attacks.
Network Security Issues
Computer crime is any crime in which a computer is the object of the crime. The computer may have been used as a tool to commit another crime, or as an object of value. This is such as personal information. “Computer security” refers to the protection of computers from this kind of criminal activity.
The following are some examples of computer crimes:
1. Using a computer to gain unauthorized access to (or interfere with) a system or network. This is such as making a computer perform at an unusually slow rate. Also, sending messages over an Internet connection interferes with other users’ ability to use that connection.
2. Using a computer to gain unauthorized access to (or interfere with) another user’s files or data;
3. Using a computer to gain access to a system or network without proper authorization and cause damage.
4. Distributing viruses, worms, or other malicious computer programs.
5. Using a computer in any way that violates federal, state, or local laws.
Cryptography and Network Security Behrouz Solution: Intrusion Detection Systems
An IPS differ from an IDS in that it actively protects the system from attacks. An intrusion prevention system (IPS) differs from an intrusion detection system (IDS). Because it actively protects the system from attacks. The following are some examples of Intrusion prevention systems:
A firewall blocks traffic from getting into and out of a protected network. Firewalls can be implemented in hardware, software, and/or firmware. Hardware firewalls can be implemented on both routers and standalone devices called personal firewall appliances.
Also, software firewalls are available as host-based software products. Also, it could be application-layer proxy servers integrated into operating systems. A router is a device that directs traffic between networks.
Hence, some firewalls block all traffic except that which is expressly permitted by the administrator of the firewall. But others have no administrator-set restrictions!
