...Under what conditions should you consider implementing a honeypot? A honey pot is a live server with intentional vulnerabilities built in and connected to an organization’s network (Hallbery, 2014). It may be protected with a firewall although the organization may want the attackers to have some access or there may be some monitoring capability done carefully so that the monitoring is not evident to the attacker. A honeypot has pretty much no special features but several reasons for implementation. For instance, a honeypot may be used to provide an attractive but diversionary playground, hoping that the attacker will leave the real system alone (Pfleeger, 2009). In addition, it may also be used to lure attackers to a place in which security personnel may be able to learn enough to identify and stop the attacker or to watch what attackers do in order to learn about new attacks so that the organization can strengthen defenses against these new attacks (Pfleeger, 2009). However, putting up a believable, attractive false environment as well as confining and monitoring the attacker surreptitiously are difficult features of a honeypot. Under what conditions should you not operate a honeypot? Honeypots are potentially very useful for organizations that have the necessary resources to maintain them. Organizations that do not have the necessary security personnel to maintain and closely monitor a honeypot must not operate one because attackers may in turn use it to attack a third...

...signatures, and behavior-based IDPS collect data from normal traffic and establish a baseline. 5. A switched-port analysis port is a data port on a switched device that copies all designated traffic from the switch device so the traffic can be stored and analyzed for IDPS. 6. In the Centralized control strategy all IDPS control functions are implemented and managed in a central location. Fully-Distributed is the opposite of Centralized, and in this strategy each monitoring site uses its own paired sensors to perform its own control functions to complete necessary detection, reaction, and response functions. 7. Honeypots are decoy systems designed to lure potential attackers away from critical systems. When more than one honeypot is connected to a number of honey pot systems on a subnet it’s called a honeynet. 8. A padded-cell is a tougher honeypot, when its detected attackers it smoothly sends them to a special stimulated environment where they can no longer cause harm. 9. Network footprinting is the organized research of the internet addresses owned or controlled by a target organization. 10.

...between an IDS and honeypot in terms of their functionality? Ans: The difference between the IDA and the Honeypot in terms of their functionality are as : IDS Functionality: IDS collect the information from different systems and the network resources for possible security problems. IDS collect and explore the information from the different parts of the computers or network and identify its potential security holes. The Instruction Detection System comprise from both the Internal and External organizations. Deployment of IDS is easier and doesn’t affect the system resources. NIDS detect many attacks like TCP SYN attack, fragmented packet attack by checking the headers of the packets. IDS have real time...

...1. PENDAHULUAN Honeypot merupakan sebuah sistem atau komputer yang sengaja dijadikan umpan untuk menjadi target serangan dari penyerang (attacker). Komputer tersebut melayani serangan yang dilakukan oleh attacker dalam melakukan penetrasi terhadap server tersebut. Honeypot akan memberikan data palsu apabila ada hal aneh yang yang akan masuk ke dalam sistem atau server. Secara teori Honeypot tidak akan mencatat trafik yang legal. Sehingga dapat dilihat bahwa yang berinteraksi dengan Honeypot adalah user yang menggunakan sumber daya sistem yang digunakan secara ilegal. Jadi Honeypot seolah-olah menjadi sistem yang berhasil disusupi oleh attacker, padahal penyerang tidak masuk ke sistem sebenarnya, tetapi masuk ke sistem yang palsu. Salah satu software Honeypot yang terkenal dan banyak dipakai adalah Honeyd. Ia akan menjebak attacker dengan membuat server-server palsu dengan bermacam- macam jenis sistem operasi seperti Windows, Linux, Unix, Mac Os dan bahkan cisco router dengan berbagi layanan seperti FTP, Web, Server dan sebagainya. Salah satu kelebihan Honeyd adalah mengemulasikan banyak server dan layanan servis palsu hanya pada satu unit komputer atau server sehingga akan menghemat resource. Sistem keamanan firewall tidaklah cukup untuk meminimalkan terjadinya serangan terhadap suatu jaringan komputer. Banyak serangan yang terjadi pada jaringan komputer dapat diketahui setelah adanya kejadian-kejadian yang aneh pada jaringan. Para administrator tidak...

...Honeypots Honeypots Kathleen Schwartz Student, Rasmussen College N430/CIS4385C Section 01 Computer Forensics Honeypots A Honeypot is a decoy system or server that will gather information in regards to an intruder or attack that is attempting to infiltrate the system. The Honeypot will attract the attacker so they attack the decoy server or system and not the actual server or system. When the attack is happening the administrators can research the attack and learn what it is doing in order to stop this attack from entering the actual system. The pro for using a Honeypot is that the attacker will most likely hit the decoy first and this gives the IT staff time to research the attack and learn from it. The con is that this cannot replace security within the system. Using a Honeypot may make the administrators feel comfortable and they may not catch actual attacks to the system. They can also be expensive to setup and being that they may not work it might not be worth the cost. When using this for a forensic investigation it could be used to set up a decoy system in an attempt to draw in an attacker that is currently being investigated. The information could be collected and used against the attacker in court. It may also be used to be able to actually catch an attacker that has been intruding systems. Honeypots can be useful in forensic investigations because the investigators can gather information and there are no actually systems being harmed during this investigation...

...Technological University Delhi, India seemachandna64@gmail.com Abstract—Nowadays, Botnets pose a major threat to the security of online ecosystems and computing assets. A Botnet is a network of computers which are compromised under the influence of Bot (malware) code. This paper clarifies Botnet phenomenon and discusses Botnet mechanism, Botnet architecture and Botnet detection techniques. Botnet detection techniques can be categorized into six classes: honey pot based, signature-based, mining-based, anomaly-based, DNS-based and network-based. It provides a brief comparison of the above mentioned Botnet detection techniques. Finally, we discuss the importance of honeypot research to detect the infection vector and dealing with new Botnet approaches in the near future. Keywords- Botnet; Bot; Malware; Malicious code; P2P; Honeypot functions programmed by the Bot-master in automated way. Bots can receive commands from the Bot-master and work according to those commands to perform many cyber crimes for example phishing [26], malware dissemination, Distributed Denial of Service attack (DDoS) attack, identity theft etc. The process of Botnet can be broadly divided into three parts: (1) Searching: searching for vulnerable and unprotected computers. (2) Distributing: the Bot code is distributed to the computers (targets), so the targets become Bots. (3) Sign-on: the Bots connect to Botmaster and become ready to receive command and control traffic...

...company is applying an Intrusion Protection System (IPS). Only detecting the intrusion will not be enough for this business as it will be too late until we know about it. Real time protection is must for this kind of business. IPS generally detects, logs, and then blocks known intrusions or anomalous network activity. False- positives are an issue and will result in a self-inflicted denial of service condition. The company is also applying honeypot where they re-route the suspicions network activity where they collect and analyze data about the attacks and gather more details about the potential attacks. This is called ‘Research Honeypot’. This is very important to further avoid such suspicious activities. 3.

...EMAIL TRACING AND SPOOFING Abstract : E-mail spoofing is the forgery of an e-mail header so that the message appears to have originated from someone or somewhere other than the actual source. Distributors of spam often use spoofing in an attempt to get recipients to open, and possibly even respond to, their solicitations. Spoofing can be used legitimately. Classic examples of senders who might prefer to disguise the source of the e-mail include a sender reporting mistreatment by a spouse to a welfare agency or a "whistle-blower" who fears retaliation. However, spoofing anyone other than yourself is illegal in some jurisdictions. In this report we will study some ways of email spoofing as well as ways of tracing the spoofed email back. 1. INTRODUCTION Spoofing refers to the act of using imitation to make parody of another work of media or entertainment. Similarly, in the digital world too, the word spoofing is used to highlight the act of tricking and fooling the unaware netizens through utterly believable imitations of trusted service providers. Spoofing is basically of 4 types: 1) URL spoofing 2) Referral spoofing 3) Caller ID spoofing 4) E-mail address spoofing In this report we will be dealing with only email address spoofing.This will include a detailed study of the techniques used in spoofing and the techniques used to trace the spammers indulging in the malicious act of email spoofing. 2. EMAIL SPOOFING Email spoofing is the act of sending an email that...

...Fully distributed control strategies are applied at the physical location of component and each site uses its own paired sensors to perform its own control functions to achieve the necessary detection, reaction and response functions. Partially distributed control strategies combine centralized and fully distributed factors. Each site can analyze and respond to local threats, while the information is sent to the hierarchical central facility enables the organization to detect widespread attacks. 7. What is a honeypot? How is it different form a honeynet? P325 A honeypot is a decoy network meant to deter attackers from an organization’s critical systems on their network. A honeynet, or entire subnetwork, has fake services that portray well-known services, but is designed to look vulnerable to attacks. 8. How does a padded cell system differ from a honeypot? P325 A padded cell IS a honeypot that has been protected so it cannot be easily compromised, aka a hardened honeypot. 9. What is network footprinting? What is network fingerprinting? How are they related? P296 Footprinting is any activity that can obtain information on a company and its network activities and assets. Fingerprinting scans network locales for active systems and identifies the network services offered on the host system. 10.

...(EC-Council, 2010, p.29). 2. Load balancing: The university needs to implement load balancing which would mitigate a DDoS attack and improve normal performance as well. They should advance in and maintain the computers that can be positioned into service quickly in the event that the registration server or other services server is disabled (hot spares) (cert.org, 1997). 3. Throttling: When an attack is being carried out, throttling will prevent servers from going down. This will throttle incoming traffic such that number and load of requests for the service will be safe for the server (princeton.edu, 2004). Deflect Attacks: They can intentionally set up systems with limited security, which is called Honeypots, to be an invitation for an attack. This Honeypots serves to deflect attacks from reaching the real protected systems. In addition, this system will help the network administrator of the University to learn and record software tools and types of attacks the attacker is using (princeton.edu, 2004). 4.

...Network Security & Ethical Hacking ------------------------------------------------- ------------------------------------------------- Neal Patrick and his friends did not realise they were doing anything unethical, in fact: when asked by Congress “At what point he questioned the ethics of his actions” – he answered “Once the FBI knocked upon my door.” “I have found that inadequate network security is usually caused by a failure to implement security policies and make use of the security tools that are readily available. It’s vital that companies complete professional risk assessments and develop comprehensive security plans and infrastructures that are publicly supported by upper management” Network security is not only about the WAN (Wide Area Network) but also the LAN (Local Area Network) as the two go hand in hand. It is possible to not only have an attack from the Internet but also internally. The moment any form of computer device becomes network capable or dependent of some form of network function, there is a given need for protection to safeguard the flow of information to and from the said device on a given network whether public or private and/or from a trusted to non-trusted source. The problem with locking down a network tightly is the administrative overhead it creates. The more secure the network becomes the greater the need is for someone or a team to administrate this. Eventually you would reach a point where it becomes impossible for the end-user...

...more on the negative side. 56.6% of all the people I asked had positive views on the impacts on tourism on the New Forest. 26.6% of the people didn’t know and couldn’t decide if it was more positive or negative. 16.6% of the people had negative views on tourism in the New Forest. When I did the questionnaire I had a total of 16 residents and 14 tourists so the results that I received were fairly even with the numbers. I noticed that the environmental impacts of tourism in Lyndhurst are negative. I found this out because after looking at my EQS (Environmental Quality Survey) graphs I noticed that there are some negative impacts, like some areas having bad air quality and noise levels in certain areas being very high. Since Lyndhurst is a honeypot site, a lot of cars were passing through, which can cause some levels of pollution. Furthermore the majority of the transport that people used was cars and buses. This can fill up the roads and make it harder for people to use transport. Also because there are so many tourists it can get quite crowded which then makes it hard to move around. When I was in Lyndhurst I found that for every resident there was also a tourist. Also the litter count in Lyndhurst is quite high, according to my results on the EQS. On the high streets of Lyndhurst the litter count was much higher than the side streets. The litter count was probably caused by the tourists that visit Lyndhurst. There were many food wrappers and drink bottles and cans. Also, tourism...
