The periodic assessment of risk to agency operations or assets resulting from the operation of an information system is an important activity. It summarizes the risks associated with the vulnerabilities identified during the vulnerability scan. Impact refers to the magnitude of potential harm that may be caused by successful exploitation. It is determined by the value of the resource at risk, both in terms of its inherent (replacement) value, its importance (criticality) to business missions, and the sensitivity of data contained within the system. The results of the system security categorization estimations for each system, is used as an aid to determining individual impact estimations for each finding. The level of impact is rated

ICMP Timestamp Request Remote Date Disclosure has risk factor none. Solution is to filter out the ICMP timestamp requests (13), and the outgoing ICMP timestamp replies (14). For host 172.17.20.1 number of Open ports found are 5, high is 1, no medium and 8 low vulnerabilities were found. ICMP Timestamp Request Remote Date Disclosure data is same. An NTP server is listening on the remote host. It provides information about the current date and time of the remote system and may provide system information and has no risk factor. A telnet server is running on this port. The remote host is running a Telnet server over an unencrypted channel. Using Telnet over an unencrypted channel is not recommended as logins, passwords and commands are transferred in clear text. An attacker may eavesdrop on a Telnet session and obtain credentials or other sensitive information. Use of SSH is preferred nowadays as it protects credentials from eavesdropping and can tunnel additional data streams such as the X11 …show more content…
Name of Operating System is Microsoft Windows Server 2003 Service Pack 1. MS08-067: Microsoft Windows Server Service Crafted RPC Request Handling Remote Code Execution (958644) (uncredentialed check) i.e. the remote host is vulnerable to a buffer overrun in the 'Server' service that may allow an attacker to execute arbitrary code on the remote host with the 'System' privileges and risk factor is critical. The remote host implements TCP timestamps, as defined by RFC1323. A side effect of this feature is that the uptime of the remote host can sometimes be computed. The remote host seems to be a VMware virtual machine. The manufacturer can be deduced from the Ethernet OUI. It is possible to enumerate CPE names that matched on the remote system having risk factor none. A DCE/RPC service is running on the remote host with risk factor none. An ncacn http server is running on this port and a COM+ Internet Services (CIS) server is listening on this port. COM+ Internet Services are RPC over HTTP tunneling and require IIS to operate. CIS ports shouldn't be visible on internet but only behind a firewall. Also a DCE/RPC service is running on the remote host. It is also possible to obtain the network name of the remote host. The remote service understands the CIFS (Common Internet File System) or Server Message Block (SMB) protocol, used to provide shared access to files,
In Part 1 of the lab, a solar cell was created and tested for its capability to conduct electricity. After researching the processes that contribute to the conductive property, it was found that the oxidized substance is the dye, as it donates an excited electron to the titanium oxide. Consequently, titanium oxide is reduced before it donates an electron to the cathode. The electrolyte solution was found to replenish the dye with electrons so it could continue to act as a reducing agent.
The attack is carried out on a closed environment using a local web server to host the
Lab one introduces the basic concepts and processes of remote sensing and gives a better understanding of multiband images, color compositing, and contrast enhancement. The following were the objectives for the lab to help introduce these concepts and processes:
Many HUD requirements are met with multiple e-mails requesting a change or an exception. Every response from the city explaining why we cannot make an exception initiates multiple e-mails explaining why we should make this client and exception. This is so time consuming.
After initial intrusion malicious software is installed on victim host that is re-ferred as RAT (remote access Trojan). RAT takes the responsibility to connect with attacker and regularly performed the actions that instructed by attacker. At this intruder take the full command and control (C2) over target host. The fact is that the initial connection is established by victim host, not by the attacker [6]. This will happens mainly for two reasons: (i) organizations firewall usually allows the connections initialized by internal hosts, and (ii) this will help the attacker to not to detected easily. Because intrusion detection systems [7] can easily detect the extremely suspicious activity such as downloads from outside hosts.
Usage of mobile phone to connect to social media is growing all over the world. Nowadays smartphones come with numerous health-consciousness apps, too. This study is to find out users’ preference between networking and health while choosing mobile phone.
In this section we first briefly explain the properties of a first-order Delta Sigma modulated bit-stream. Based on these properties, we propose the P-N pair method to process the Delta Sigma modulated bit-streams.
We thank the reviewer for the carefully review and important comments made on the manuscript. We hope we have improved the manuscript.
This week’s lab objective is for the student to examine a memory dump from Jane’s computer (BlackSuit Case from week 1) to answer the following: Ascertain Jane’s IP address at the time of the memory acquisition; Determine if there are any active connections and report on their legitimacy; Identify listening ports, and report any suspicious activity. To accomplish this goal, the student is given the memory dump collected by a first responder in the investigation as well as access to two tools contained within the provided EnCase VM; RedLine and Volatility to complete their investigation with.
With the increase in threats over the past few years it is no longer acceptable for an organization to feel data is protected
Translation (NAT). Such a system often use the IP range 192.168.0.0/16 (defined in RFCWindows Others Unknown
Port scans: A program will be utilized by programmers to interface with the framework and figure out what TCP or UDP ports are open and vulnerable against attack, which is called as scanner. These scanners will discover which PC on the system is vulnerable against attack and focus the services running over the
This paper is presenting types of attacks in security of TCP/IP protocol and also defense to security problems. Flaws in such system are due to attackers’ access over machine and due to insecurity of machine. Paper proposed solutions to the problems and discuss problems without considering their implementation.
The main significance of the analysis of the data is to determine the existing potential vulnerabilities in a network and to identify the host details. As per the current scenario, there are no tools to analyze a particular data obtained through scanning. The new or existing tool will help to identify the potential risk in the existing network of industrial control systems. We can also analyze the infected host, which is affected by new vulnerability and also can take precautions to overcome this vulnerability by implementing more security in our devices. Also able to determine the software, FTP servers connected to the internet.
