What is Bug Bounty


Bug Bounty


Web Application Development companies, Online Software Development companies, big websites like facebook, Yahoo, Google, Microsoft etc pay some amount to hackers, cyber security people who help them in finding and/or fixing the cyber security vulnerabilities in their websites, applications etc.  Bug bounty programs are specially useful before launching the web application in the market.

Bug Bounty program was initiated by Jarrett Ridlinghafer and he coined the term "Big Bounty" while he was working at Netscape as technical support engineer.

Cyber Security researchers are hired by almost all big internet companies to find and fix the vulnerabilities. Companies run the Bug Bounty programs  to patch the flaws, security holes and cyber security people get rewards in the form of money or  gifts along with the good recognition. Companies publish the cyber security researcher name on their corporate website under "Hall of Fame" category and acknowledge their efforts openly. Bug Bounty programs are very helpful in making internet browsing, online shopping etc  more secure.

Nowadays companies are increasing the rewards to identify and patching the vulnerabilities. Cyber Security researchers may earn from $500 to $ 5000 and sometimes even more it all depends upon the complexity.

Beware - Finding the vulnerability does not mean that you publish the cyber security issues anywhere on any website or posting about security holes  on various internet forums to get publicity.  One must be responsible enough and should disclose such findings only to the company's Cyber Security Team.

HoneyPots, HoneyNet : Useful to protect computer, computer network from being hacked

Honeypot in Information Technology is as sweet as its name, I heard a story about natural tendency of greed. It is said that to trap the monkey, people use to have a earthen pot and put some chickpeas (Chana) into it. When monkey approaches the pot to pick chickpeas and drops its hand inside the earthen pot. His hand is full of chickpeas as he wants to eat those but due to closed hand (fist)he is unable to take out his hand out of pot. Now he is trapped and people catch him.

Likewise to nab the hackers, computer intruders- Information Security guys developed Honeypots. Honeypot is a trap which is set to lure the attackers, detect and gather malicious activities of computer hackers, intruders and generating alerts. The activities of attackers provides valuable information for analyzing their attacking techniques and methods. Because honeypots only capture and archive data and requests coming in to them, they do not add extra burden to existing network bandwidth.    Honeypot may be standalone machine or can be a network of some computers. If it is network of computers then it is called as HoneyNet. Honeypot/HoneyNet is isolated from the actual network of the organization and it is monitored to collect all the activities of the attacker. Honeypot can be called as modern times Detective.

Honeypot monitors and gathers all the activities of the computer attackers e g how hackers probe, how they get access into the computer system,  their attacking methodologies. Honeypot not only useful in cyber security research as new attack approaches, methodologies are available to cyber security research teams but honeypots are very helpful to Forensic department.

Let us understand it by an example- Traffic at some specific port say 110 can be directed to a web server as a normal traffic but rest of the web server traffic can be directed to honeypot to gather information. If honeypot is deployed properly and successful then computer hacker will have no clue that he is being trapped.
Honeypots can be divided into two categories:
  1. Low Interaction Honeypots or Productions Honeypots 
  2. High Interaction Honeypots
1. Low Interaction or Production Honeypots normally used by small size companies and are easy to deploy. These honeypots provide basic information about cyber security threats.

2. High Interaction Honeypots are complex and used for research purposes.

Computer Protection Steps which can be implemented by a non -IT person/ How to avoid intrusion in a computer

 
Earlier when technology was not advanced, human beings used to work in paper files and those documents used to be kept safely in almirah and if document was of utmost important that time there used to be a strong lock in order to have more protection and at times protection of room was also required. Whenever some mischievous people intended to steal the documents, they used to scan the building, room etc, purpose was to find out weakness in the building, room and almirah. Or we can understand it like if you do not lock your vehicle, it is insecure. Now we are living in a era of technology so things have changed a lot. Presently we use computer to store our documents, files and important conversation etc. So we need to protect our computer likewise, hackers try to find out loopholes in the computer and technology. Therefore you need to maintain your computer security in order to block all vulnerabilities.

Here are few suggestions for best computer protection which can be implemented to avoid intrusion into the computer:

Make sure that firewall is turned on. It is very vital tool to stop a cracker from gaining access to your computer. If it is home computer then single firewall is sufficient but in case of a organization's computer where data is more crucial, some hardware tools ie router which also comes with firewalls.


Install a legal and antivirus software, avoid using pirated one. Pirated antivirus program is not able to provide required protection. Do not forget to upgrade anti viruse or you can configure those for auto upgrade option. New viruses also come on daily basis, so regularly check the antivirus manufacturer's website for updates. Most antivirus programs are sold with annual subscriptions, which can be renewed as needed 

A computer virus is the common problem. Computer virus gets install into your computer system and as you run a program to which virus is already attached itself. Virus reproduces multiple copies of itself from your computer only.
One good example can be of "Trojan horse" programs. Trojan horse programs are similar to viruses, but these do not reproduce their multiple copies. Normally Trojan horses tries to install a malicious program into your computer. Sometimes due to malicious program into your computer, it may start doing some very funny activities like auto booting itself. If it  is your home computer the you may try some freely available anti virus programs like AVG, avast etc for best computer protection. Well established companies do offer free antivirus programs for best computer protection specially for home users.

Install anti spyware software, it stops a malicious user from peering into your computer. Malicious users quietly send spyware program to your computer so that without your consent they can theft the data or can produce advertisement popup whenever you browse internet or access social networking websites. Nowadays most of the operating system comes with inbuilt anti spyware programs but should be keep on upgrading your operating system in order to upgrade anti spyware.


Attentively download anything from internet or do not open an attachment which comes via email as it may contain some harmful exe (executable) files. As you click on those, they install malicious code in to your computer.

Upgrade operating system on regular basis because manufacturer periodically fix the security holes.

For emails try to use Microsoft outlook or windows email as they are quite capable to restrict the virus entry.


Do not forget to turn off your computer once you finish your work. Sometimes crime could take place just because the computer, built-in camera or printer etc was on. Sometimes crackers use your computer resources without your knowledge and they may indulge in some illegal activity.

Take regular backup, anytime anything may happen so better to be alert than sorry.

Nowadays almost everyone is on internet, visually roaming here and there, downloading and uploading files, If you are not careful then crackers may crash your computer, can send pop ups of bizarre messages.


Delete unknown emails; never click on advertisements links, or any link which directs you to some other website.


Computer must be password protected and password should be toughest so that it will be hard to crack.

Email Security

Your organization security is at substantial risk if you have not implemented email security policy. Daily we all receive emails which con...
