Traditional Honeypot DNS

In conclusion, this paper discussed the popular topic of active defense and how traditional defenses aren’t very adequate anymore. Next this paper discussed honeypots used to deceive attackers. This paper also discussed Computer Network Attack and Computer Network Defense and the legal impacts between the two. Lastly this paper discussed the pros and cons of active

In recent year’s law and policy makers have expressed alarm at the exponentially growing threat of malicious traffic that has been traveling across the Internet. While most agree that something needs to be done, consensus falls apart around the issues pertaining to cybersecurity policies, laws and enforcement. This policy paper will briefly discuss the current state of our cybersecurity infrastructure. The terms of malicious traffic, liability and its forms will defined, key components will be introduced, the roles that the Internet Service Provider (ISP), software producer, end user, operating systems developer play in this process will be examined and key legislation will be mentioned. These key factors and research herein, help to supply that the liability should lie with the Internet Service Provider should be sought.

Network Security - Networks are classified into many types like shared and non-shared, public or private, small area or large area networks and each of them have a number of security threats to deal with. Problems associated with the network level security comprise of DNS attacks, Sniffer attacks, issue of reused IP address, etc. A Domain Name Server (DNS) server performs the translation of a domain name to an IP address. Since the domain names are much easier to remember. Hence, the DNS servers are needed. But there are cases when having called the server by name, the user has been routed to some other evil cloud instead of the one he asked for and hence using IP address is not always feasible. Although using DNS security measures like:

DNS is critical in the footprinting of a target network. It can sometimes save the attacker a lot of time, or at least corroborate other information that has been gathered. DNS is also a target for several types of attack.

Honeypot is usually used as network intrusion detection systems. A honeypot will contain fake/false data and information and performance like a computer or server to trap any unauthorized use of information system. Normally honeypot will be isolated from “real network” and used for monitor and alarm system to alert network administrator if detect any malicious or suspicious activity.

Together with your approval, I wish to investigate these cyberattacks involving dealing with threats that range between malicious codes, which are referred to as malware and spyware, to computer viruses. All of the threats to computer networks come from the web and they are often intentional, having been manufactured by people with malicious intent. There is a deadline on the report which carries a proposed timeline and budget necessary in order to complete the investigation project. A list of sources has been

Denial of Service (DoS) attack is a very common cyber menace that renders websites and other online means inaccessible to intended users. There are various types of DoS threats and nearly all directly target the core server structure. Others abuse weaknesses in application and communication proprieties. DoS is also used as a cover-up for other wicked actions, and to take down security applications like web firewalls. A prosperous DoS attack is very obvious and impacts the entire online user base.

The denial of service attack has become prominent against banks. The sinister attack claimed two victims and they were banks. According to Wells Fargo bank and PNC bank customers slow internet traffic when trying to access their online accounts. This was due mainly to an unusual high amount of traffic causing slow internet access to the banks website. Wells Fargo and PNC both launched an investigation into the incident that was annoyance for the most part to customers trying to conduct business online. Their findings were that a Distributed Denial of Service (DDoS) attack against both banks causing a disruption in service to customer. According to Koga, Okazaki, Watanabe, and Park (2011) denial of service poses security problems on the internet. They recommend that countermeasure should take place to trace the attackers and stop the attacks (p. 29).

The consultant will validate targets in the discovery IP address range listed in the scope. The consultant may perform this step to attempt to identify live hosts for future testing efforts. The consultant may perform such activities as:

networks are also being targeted by malicious activity” [Overall statistics for 2014]. Many of the technologies used within these systems are now being exploited by criminals trying to access information and perform other criminal activities. The main reason for this is because most of the infrastructure in place is controlled by IT systems and the security systems in place

The Internet is a global public network and it is the Universal source of information. It has become a popular medium for commercial activities. Millions of dollars of transactions occur daily in many financial organizations through Internet. The internet along with digital technologies has taken human life into much higher levels of sophistication and ease. The growth of Internet has brought about great benefits to the modern society; meanwhile, the rapidly increasing connectivity and accessibility to the Internet has posed a security threat. With the tremendous growth of network-based services and sensitive information on networks, network security is getting more and more import than ever. The attacks on the Internet have become both more prolific and easier to implement because of the ubiquity of the Internet and the pervasiveness of easy-to-use operating systems and development environments.

The security reasons on how easy and efficient DDoS attacks are fairly simple. When a user “Smurfs” you, the hacker has begun to flood your router. The flooding of the router is forced by an Internet Control Message Protocol (ICMP); the flooding is coming from a volume of different packet sizes (Ashwini). The packets destination IP address is the broadcast address; this is causing the router to broadcast your ICMP packet’s

The first and most important fact is the acknowledgment that DNS was not designed or implemented with a security centric focus (Yang, Osterweil, Massey, Lu, & Zhang, n.d. p. 2). As a result of the lack of security focus during DNS development, DNS was not design for cryptographic scalability, heterogeneity, deployment, operation, and monitoring (Yang, Osterweil, Massey, Lu, & Zhang, n.d. pp. 13 & 14). Retrofitting DNS with security extensions (DNSSEC) has been a difficult, complicated, and difficult to deploy (Yang, Osterweil, Massey, Lu, & Zhang, n.d. p. 3).

Cost for increasing security to DNS varies depending on the kind of name server used. When the data is static then PK-DNSSEC is suitable and when the data is dynamic, better option would be to consider SK-DNSSEC. Caching resolvers computational cost is large in PK-DNSSEC and non-recursive servers computational cost is high in SK-DNSSEC [2]. Hybrid approach is used to eliminate these computational costs.

Abstract—Mobile Ad-hoc Network (MANET) is a kind of wireless network. A Wireless ad-hoc network is a temporary network with no network infrastructure. The nodes communicate with each other, they co-operate by forwarding data packets to other nodes in the network. Thus the nodes find a path to the destination node using routing protocols. Due to the security vulnerabilities of the routing protocols, wireless ad-hoc networks are unprotected to attacks of the malicious nodes. One of these attacks is the Sinkhole Attack. Sinkhole attack is a kind of routing attack in MANET. A sinkhole node tries to attract all the network packets to it-self from all neighboring nodes. This paper focuses on to detect and prevent sinkhole node. By using a hybrid detection technique which combines the advantages of both reactive and proactive routing Protocol to detect the
