One of the many devices that can be used to encase data within an encrypted tunnel is through the use of a VPN. As a network device, a VPN is used to transmit data between two private locations (Microsoft 2008). Through the use of the publically accessed network, the data transmitted via a VPN is considered to be safer because the connections that make up the session are dedicated and the encryption used can vary depending on the security protocol (Microsoft 2014). Users can set up the encryption on these connections to a multitude of different levels based on the amount of security they would like to have. The choices of security protocols that can be used are from the lowest levels that only create tunneling such as Point to Point Tunneling Protocol (PPTP) or Layer 2 Tunneling Protocol (L2TP) to the more advance setups such as Secure Shell (SSH) and Secure Sockets Layer (SSL) or Transport Layer Security (TLS). As stated, these connection can be used based on the need of privacy and even protocols such as the L2TP can be combined with the IP Security protocol (IPsec) to create a L2TP/IPsec which operates as a joint operation to create the tunnel via the L2TP and to encrypt/error check with the IPsec (Microsoft 2014). Another avenue is the use of encrypting the channel rather than the data, this is used through the SSH protocol and this works by routing data through a SSH client created channel which is used to safeguard the transmitted data.
One device users can use to monitor data being transmitted is a passive Intrusion Detection Systems or IDS, these systems is a device that will watch over all data that is going in and out of the network (IDS 2014). Activity is analyzed by the system and over time, a behavior will be...

The SIEM is a log management system where every network device, server or workstation will send their logs for storage, correlation and analysis. The analysis will provide alerts similar to the NIDS and HIDS. In addition, the log correlation could be used to help track where and when malicious activity has occurred and on what system(s) the activity was seen. The combination of the NIDS, HIDS and SIEM will provide a good array of detection for malicious users, software or unauthorized system access.
IDS is a device or software application that monitors a network for an unauthorised attack.
VPN – Virtual Private Network - a method employing encryption to provide secure access to a remote computer over the Internet.
The Aim Higher College’s system administrators and network engineers have described seeing some strange behaviors such as high levels of traffic from many hosts that are causing system outages. The web servers of the college have been shutting down frequently by this traffic, it must be from a hacker group trying to attack the school with malicious software. I will review the network traffic from the college’s intrusion detection system and use an intrusion prevention system to block off these threats from the hackers.
In 1980, James Anderson’s paper, Computer Security Threat Monitoring and Surveillance, bore the notion of intrusion detection. Through government funding and serious corporate interest allowed for intrusion detection systems(IDS) to develope into their current state. So what exactly is IDS? An IDS is used to detect malicious network traffic and computer usage through attack signatures. The IDS watches for attacks not only from incoming internet traffic but also for attacks that originate in the system. When a potential attack is detected the IDS logs the information and sends an alert to the console. How the alert is detected and handled at is dependent on the type of IDS in place. Through this paper we will discuss the different types of IDS and how they detect and handle the alerts, the difference between a passive and a reactive system and some general IDS intrusion invasion techniques.

Moreover, VPN allows the creation a secure private network over a public network such as the Internet.
Although Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS) have been grouped together here (IDPS), there are distinctions between them. On the most basic level, both will monitor the network...
There are many types of routing or data/packet retransmitting hardware and devices that networks can utilize for security purposes. Some use one or a combination for data transfer. However, each poses a level or type of vulnerabilities, additional unwanted threats, and countless types of risk. The quintessential design is to provide a means to controlling the flow of packet transfer. The main function of the switch, router, gateways, or hubs is having the ability to process and forward data packets on the network. The creation and function is to ensure that each having their own unique functions and configurations which makes one a more viable optional choice over the next for ensuring data forwarding. For example, large networks will need routing protocols that will send the data packet to the intended destination and not broadcast it throughout the entire network.
When someone suspects that an unauthorized, unacceptable, or unlawful event has occurred involving an organization’s computer networks or data-processing equipment Computer security incidents are normally identified. Initially, the incident may be reported by an ultimate user, detected by a system administrator, identified by IDS alerts, or discovered
Virtual private networks (VPN) provide an encrypted connection between distributed sites over a public network (e.g., the Internet). By contrast, a private network uses dedicated circuits and possibly encryption. The basic idea is to provide an encrypted IP tunnel through the Internet that permits distributed sites to communicate securely. VPN's permit secure, encrypted connections between a company's private network and remote users through a third-party service provider. A VPN can grow to accommodate more users and different locations much easier than a leased line. In fact, scalability is a major advantage that VPN's have over typical leased lines (dedicated circuits). Unlike with leased lines, where the cost increases in proportion to the distances involved, the geographic locations of each office matter little in the creation of a VPN.
A Virtual Private Network, more commonly known as VPN, is a type of technology that provides secure private connection for users who connect to public networks, such as the Internet or company network. It is a safe and secured channel through which data are transmitted without exposing these data to anyone.
Without proper protection, any part of any network can be susceptible to attacks or unauthorized activity. Routers, switches, and hosts can all be violated by professional hackers, company competitors. In fact, according to several studies, more than half of all network attacks are waged internally. To determine the best ways to protect against attacks, we should understand the many types of attacks that can be instigated and the damage that these attacks can cause to data. The most common types of attacks include Denial of Service (DoS), password, an...
Implement a system Intrusion Detection/Prevention System (IDS/IPS): - Make the investment in an IDS/IPS to distinguish and prevent potential system dangers. sensors ought to be circulated all through the system, with a specific focus on general society untrusted section. Take alerts very seriously.
