Can you imagine a fridge which checks its egg tray and reminds you to buy eggs in your mobile phone or orders the nearby grocery store to supply eggs to your home; an air conditioner that can be switched on or off using your mobile phone; or a car that automatically reminds you about filling fuel as you approach a fuel pump? This is being made possible using Internet of Things (IoT). IoT is the concept of connecting all devices like mobile phones, fridges, cars, air conditioners, lamps, wearable devices, etc. To the internet. Each device is provided with a unique IP address which identifies it allows it to transfer data over Internet without human intervention. The huge increase in the number of IP addresses due to the implementation of IPv6 supports the introduction of this technology. The IoT can be used to monitor health of patients and inform the doctor about an urgency, applied to things which helps us reduce wastage like power, water, etc. and improve the way we work and live...

  Threats to computers and networks are a major issue as long as information is accessible and transferred across the Internet. Different defense and detection mechanisms are developed to deal with these attacks 1.FIREWALL A firewall is a system of computer hardware and software that provides security to the computer network in an organisation. A firewall controls the incoming and outgoing network traffic by analysing the data and determining whether they should be allowed through or not, based on a rule set. Firewalls deny malicious data from entering into the computer networks. 2.ANTI-VIRUS SCANNERS Viruses, worms and Trojan horses are all examples of malicious software (malware). Antivirus tools are used to detect them and cure the infected system. Anti-virus software scans files in the computer system for known viruses and removes them if found. The antivirus software uses virus definition file containing signatures (details) of viruses and other malware that are known. When an...

  A Denial of service (DoS) attack is usually aimed at a web server. Such an attack forces the server/computer to restart. An attack in which the attacker's goal is to shut down the target server rather than stealing data is called DoS attacks. This prevents genuine users of a services/website on the web server from using that service. This attack can be done using a single computer called Denial of service (DoS) attack or using more than one computer called Distributed Denial of service (DDoS) attack. We have learned that when we type a website address in the browser and press the enter key, the browser requests for that web page from the server. DoS attacks sends large number of such requests to the server until it collapses under the load and stops functioning. A DoS attack using a computer on a network slows down the network by flooding a server with large number of requests. A DDoS attack uses multiple computers in the network that it has previously infected. These infected. T...

  Following are the major guidelines for using computers over Internet. Most of the computer viruses are spread through e-mail attachments. Do not open any e-mail attachment that you are not sure about the sender. Download files only from reputed sources. Do not use/copy software that you cannot confirm the origin. Avoid clicking on pop-up advertisements. close them instead Use USB drives with caution. Plugging someone else's USB storage into your computer or plugging your own USB storage into a computer at an Internet cafe/unsafe computer, can spread an infection through USB  storage.  Make sure the firewall is set and turned on. Use strong passwords. Change password at regular intervals. Update the virus definitions of your antivirus program periodically online. Keep a regular backup of your important files on DVD, another hard disk, etc. Be careful about giving personal data online. If you see e-mail message requests for personal data such as telephone number, address,...

  A  man in middle attack refers to an attack in which an attacker secretly intercepts electronic messages between the sender and the receiver and then captures, inserts and modifies messages during message transmission. If sender transmits messages without appropriate security, the attacker may exploit the vulnerabilities in the network to capture and modify the messages and send the modified messages to the receiver. Since the network transmission still works properly, both the sender and receiver will find it difficult to notice that the messages have been trapped or modified by an intruder. If we use such a computer for online transactions, the man in the middle may capture our bank account number and password to steal money, leading to financial loss. Encrypted connections such as HTTPS (HTTP Secure), SFTP (Secure FTP) etc. should be used for secure transactions, so that intruders cannot modify the messages. 

Phishing is a type of identity theft that occurs online. Phishing is an attempt to acquire information such as usernames, passwords and credit card details by posing as the original website, mostly that of banks and other financial institutions. Phishing websites have URLs and home pages similar to their original ones. The act of creating such a misleading website is called spoofing. People are persuaded to visit these spoofed websites through e-mails. Users are tempted to type their usernames, passwords, credit, card numbers, etc. in these web pages and lose them to these websites. These frauds use this information to steal money. Phishing is currently the most widespread financial threat on the Internet.
