Network Security Threats

Introduction A threat is dangerous for information assets. There are many threats that will pose continuous risk to individuals and organizations' information assets. This report will cover four important threats and their countermeasures. These threats include cyber threats, wireless network threats, physical threats, and threats of web browsing.

This article focuses on blocks based on public policy considerations, but there are two reasons why network blocks are configured. The first is to prevent or respond to cyber security threats. This type of blockage is common. For example, most companies are trying to stop malware from entering the network. Many Internet service providers (ISPs) provide data blocks to block malicious traffic on the network, such as from hijacked IoT devices (such as Web cameras). Filtering e-mails, such as blocking unwanted e-mails such as bulk mails and phishing e-mails, is very common. In this article we will not discuss these types of blocking.

Organizations and their information systems and networks are facing security threats due to various causes such as computer-based fraud, spy acts, vandalism, vandalism, fire, floods, and so on. The cause of the damage such as malicious code, computer hacking, DoS attack, etc. became more general, became more ambitious, more complicated. Information security is important for both the public and private sector businesses and it is important to protect critical infrastructure. In both areas, information security functions as a facilitator, for example to implement e-government or e-commerce, in order to avoid or mitigate related risks. Interconnection between public and private networks and sharing of information resources increases the difficulty of implementing access control. Distributed computing trend also weakens the effectiveness of central expert control
