Analyzing social media streams has gained importance in recent days. Visualizing the social media streams can aid in discovering new insights from the data and open up new opportunities for the government and businesses alike. In this project we have used twitter data from USA and SPAIN to show how social media streams can be explored from different perspectives.
Datasets
To run the visualization system :
To start a local server (recommended python HTTP server, hence python must be installed)
python2 python -m SimpleHTTPServer 8000
python3 python -m http.server 8000
A tool that splits a large pcap file into multiple pcap files where each pcap file contains a single tcp connection and are ordered by timestamp.
Clone the repository. Makefile is provided. Requires "tshark" to run.
apt-get install tshark
Command line switches:
./tcp_split -i test.pcap -o /root/Desktop/output -f 45.79.50.193 -j /root/Desktop/output/non_tcp.pcap
Using blockchain to implement chain of custody to preserve forensic evidence records.
The Chain of Custody form is a critical element to a forensic investigation because examiners use it to record the history of the evidence from the time it is found until the case is closed or goes to court. By keeping this record, examiners can show that the integrity of the evidence has been preserved and not open to compromise. And in the unfortunate event that evidence does become contaminated, the chain of custody will clearly identify the responsible individual.
A Chain of Custody form keeps track of three pieces of important information (in addition to all the details that uniquely identify the specific piece of evidence).
Commands Implemented :
bchoc add -c case_id -i item_id [-i item_id ...]
bchoc checkout -i item_id
bchoc checkin -i item_id
bchoc log [-r] [-n num_entries] [-c case_id] [-i item_id]
bchoc remove -i item_id -y reason [-o owner]
bchoc init
bchoc verify
A custom WordPress theme designed solely for PSI Stationery Trading LLC, UAE while interning as a Full Stack Web Developer at Freastal Technologies.
One of the most common misconception about WordPress is that it is just a blogging platform. It is NOT. While WordPress started as a blogging tool, it has evolved throughout the years into a powerful website builder and a robust content management system (CMS).
The best part about WordPress is that it’s easy to use and flexible enough to make different types of websites. That’s the main reason why WordPress has grown so much in popularity. According to a recent survey, WordPress powers 32.3% of all websites on the internet.
The project assigned was to relocate a JSP website of a wholesale company, PSI Stationery Trading LLC, Dubai, UAE to a Content-Management System (WordPress). For the same, I was instructed to create a custom responsive WordPress theme from the scratch that catered to the needs of fulfilling the design and functionalities of the website.
Multiple remote code execution vulnerabilities exist in Microsoft Server Message Block 1.0 (SMBv1) due to improper handling of certain requests. An unauthenticated, remote attacker can exploit these vulnerabilities, via a specially crafted packet, to execute arbitrary code. (CVE-2017-0143, CVE-2017-0144, CVE-2017-0145, CVE-2017-0146, CVE-2017-0148)
An information disclosure vulnerability exists in Microsoft Server Message Block 1.0 (SMBv1) due to improper handling of certain requests. An unauthenticated, remote attacker can exploit this, via a specially crafted packet, to disclose sensitive information. (CVE-2017-0147)
ETERNALBLUE, ETERNALCHAMPION, ETERNALROMANCE, and ETERNALSYNERGY are four of multiple Equation Group vulnerabilities and exploits disclosed on 2017/04/14 by a group known as the Shadow Brokers. WannaCry / WannaCrypt is a ransomware program utilizing the ETERNALBLUE exploit, and EternalRocks is a worm that utilizes seven Equation Group vulnerabilities.
A White-Box penetration testing was conducted on the Target Machines with prior permission from the concerned authorities.
The Pen-tester was assigned an IP in the same local network as that of the target machine. Efforts were placed on the identification and exploitation of security weaknesses that could allow a local attacker to gain unauthorized access to administrative data.
The attacks were conducted with the level of access that a general local user would have.
The remote Windows host is affected by an elevation of privilege vulnerability in the Security Account Manager (SAM) and Local Security Authority (Domain Policy) (LSAD) protocols due to improper authentication level negotiation over Remote Procedure Call (RPC) channels. A man-in-the-middle attacker able to intercept communications between a client and a server hosting a SAM database can exploit this to force the authentication level to downgrade, allowing the attacker to impersonate an authenticated user and access the SAM database.
Let us consider the situation of India. In India there are nearly ten telecom providers. If a customer is dissatisfied, he has other options to explore.
Different customers tend to have different requirements. Consider a population of 15 teenage boys, 15 working persons and 15 senior citizens. The teenage boys tend to spend more time on internet, the working class spends less time over both internet and voice call, and senior citizens tend to spend more time on calls as compared to teenage boys. There is a need to understand the requirements of each of the class.
The Churn Prediction Models takes into account various demographic aspects along with financial burden and usage pattern of various groups.
Attaching weightage to the features will enable the telecom industry to direct specific services towards group of customers.
Providing sufficient Quality of Service (QoS) across IP networks is becoming an increasingly important aspect of today's enterprise IT infrastructure. Not only is QoS necessary for voice and video streaming over the network, it's also an important factor in supporting the growing Internet of Things (IoT).
The Churn Prediction Model will aid the telecom service providers to concentrate to improve the QoS of services provided by them.
When looking at networking basics, understanding the way a network operates is the first step to understanding routing and switching. The network operates by connecting computers and peripherals using two pieces of equipment; switches and routers. Switches and routers, essential networking basics, enable the devices that are connected to your network to communicate with each other, as well as with other networks.
Cisco Packet Tracer is a powerful network simulation program that allows students to experiment with network behaviour and ask “what if” questions.
Packet Tracer provides simulation, visualization, authoring, assessment, and collaboration capabilities and facilitates the teaching and learning of complex technology concepts.
Packet Tracer supplements physical equipment in the classroom by allowing students to create a network with an almost unlimited number of devices, encouraging practice, discovery, and troubleshooting.
