Verify data is encrypted

Encrypt all the confidential information that you are sharing and transferring over the internet. Encrypt information such as credit card numbers, usernames, or passwords and send it securely. To verify this, look for Internet browser security lock (a small lock) next to the address bar or in the bottom right corner of your browser window. Once you are able to see this, makes sure that it should be in the locked position. Also make sure that the URL begins with https.

Data is encrypted if the lock is in the locked position. No one can intercept the data if try to intercept it if the data is locked. All information can be read if there is no lock visible and once it is intercepted. Use a password that you don’t use with protected sites if a web page such as online forum is not secure.

Use a safe and strong password

You should use strong and safe passwords for those websites which store confidential data. It is advised to you that use a different and strong password for each website that requires a login. Use a password manager if you cannot remember your passwords.

If available, enable two-factor authentication

If you enable two-factor authentication, you add an additional step for your online protection while verifying a login. Typically with two-factor authentication, after entering password, if the service does not recognize your device, you will receive a text message with a specific code to login. It is a good way of protection because no one can access your account even though one has a valid password because it requires that specific code to login.

E-mail is not encrypted

Never transmit you highly confidential data like your credit card information, passwords, and bank details over e-mail is not encrypted and any intruder may hack and read it.

Be careful while accepting or agreeing to prompts

Read and understand the agreement before clicking on the Ok button while installing any program. Cancel or close the window if you do not understand the agreement or feel that it is not necessary to install the program.

Additionally, check out for any check box that asks if it’s ok to install a third-party program, toolbar, etc. If it asks so, leave these boxes unchecked or cancel the install as these third-party programs causes more issues than good.

Be aware of phishing scams

Be aware of different types of phishing scams and techniques, which are meant to trick innocent users into providing their account information.

Stay concerned where you’re logging in from

Business: Your place of work can install key loggers or use various ways of monitoring you system when you are online. Someone who has access to this information may be able reading and recording this information. So it is recommended to you that don’t store any password in your browser if your system is shared with co-workers.

Wireless network: Your computer can be intercepted and read by someone else who is nearby when you are on a wireless network. Log onto a secure network using WEP or WPA to prevent this from happening. If you are on a home network. Make sure that it secure.

Friend’s house: Be careful if logging into an account on a friend’s computer because a computer or network you are not familiar with could unintentionally or intentionally log usernames and passwords. Never save the password information on the browser if you are logging into any site on a friend’s computer.

Use the latest browser

An outdated browser is highly insecure so use the latest version of the browser like use Microsoft Edge instead of Internet Explorer and also use alternative browser such as Google Chrome or Mozilla Firefox to stay safe.

Be attentive of those around you

Be careful of anyone’s shoulder surfing at work, school, library, or anywhere else. At such places, people may watch you filling up your confidential information like login ids and passwords. To keep your information private that display on the screen, use privacy filter for the display.

Update Internet browser plugins

Make sure all installed Internet plug-ins like Adobe Flash are up-to-date as often attackers find out security vulnerabilities through browser plugins.

Secure saved passwords

Always store passwords and login information in a secure area. Never write login information in a text file that is not encrypted or on a sticky note. Use a password manager to keep your login information secure.

Have against malware, spyware, and viruses

Give the complete protection to your device by installing an anti-virus program on it. Software programs like Trend Micro, Norton, Avira, etc. can keep your computer safe against malware, viruses, and other such infections.

If in case you don’t want to install anti-virus protection and running the latest version of Windows, run at least Windows Defender on your computer.

Is it Possible to stop IP-spoofing in the Internet?

IP-spoofing is a severe enough problem that requires serious attention. Cyber criminals have developed inexpensive IP-spoofing techniques to mount reflector attack which significantly causes and contributes to large volume DDoS attacks against various Internet infrastructure and resources. This document explains the required measures to stop IP-spoofing and the massive Distributed Denial-of-Service (DDoS) attacks that you continue to see on the Internet and why these measures are useful, what network operators, enterprises and others can do to reduce and prevent DDoS attacks and other similar threats. To prevent “spoofing” of IP addresses, there is one mechanism called anti-spoofing technologies” that network operators can implement. This article explains how you can make Internet faster and more secure so some of the tools, technologies, and reasons are covered here for implementing anti-spoofing.

DDoS attacks are executed by trading on the vulnerabilities like malware and “bots” running on unsuspecting computers. Attackers use malware and “bots” running on a targeted computer to execute a DDoS attack. To perform a DDoS attack, attackers send large number of requests at a target server which make it busy and unresponsive.  All requests typically have “spoofed” and bogus source IP addresses and when the server tries to revert on these requests it gets stuck and wait to open connections to the non-existent requesting servers.  As the attack use spoofed source IP addresses, it gets extremely difficult to track down the sources of the attacks from where they are coming.

In this scenario what seems to be an easy solution is just don’t allow packets to leave your network and travel the rest of the Internet with a spoofed IP source address.  At the very edge of the Internet, a home network or an enterprise can know precisely the range of IP addresses on its network to allow only those addresses as source addresses for outgoing packets. However, it gets very complicated and challenging in larger network but it is still very effective approach. In general, this approach is called Best Current Practice. Some people also call this approach “network ingress filtering” or “source address validation“.

Volumes of DDoS attacks are continuously growing. The real problem is ISPs don’t want to bear exceeded costs and take risks associated. They also don’t see instant benefits from deploying anti-spoofing measures. Your network is not completely secure even if your network hosts anti-spoofing measures like using ingress filtering or taking any other similar action. But you still need to deploy ingress filtering and need for better documentation and practical use cases to make risks, costs, and benefits more clear. It is also about the awareness of ISPs. They need to think if they are part of problem or victim of attack in a recent amplification reflector attack. However, this is definitely not evident and it is very difficult to track back the culprit, but there is way out to address these challenges and make visible improvements in all directions.

It is a difficult task to make a good anti-spoofing business case as it increases a sense of collective responsibility. Though anti-spoofing technique doesn’t necessarily protect a network’s own resources, but it provides benefit for the Internet as a whole. On a network it is implemented, it makes sure that the same network does not work as a launch pad for “spoofed” attacks.

In many cases, applying ingress filtering is easy and simple filters work perfectly well. However, this may not be true in case of more complex setups. There more care should be taken and detailed descriptions of pitfalls and corrective measures instructions could certainly help to overcome doubt and fear of implementing various solutions appropriately. You need t o think as a network user and find out the points where the anti-spoofing measures can be implemented more effectively. Besides that promoting egress filtering, users need to apply and follow security protocols. They should apply anti-spoofing tools and technologies. They need to install programs like AVG Internet security that can filter out malware and infectious contents to leave vulnerabilities on your network and make it safe. For more help you can ask pctech24.com.au experts to get AVG Support.

Benefits of VPN or the Virtual Private Network

Today, we live in a computer driven world. The computer is a basic requirement for leading a smart life these days. Everybody has an access to an internet connection and everybody uses it for their own different; personal or professional uses. In today’s age of technology, not having all time access to the internet can sometimes be a great obstruction in your work. And having a secure internet connection at the time you need it is of utmost importance. But how can you be sure that the unknown internet connection that you are using at the time of emergency is safe, secure, and free from and infiltration from the outsider and the data that you send or receive over this network is safe as your own personal connection. This is where VPN comes in.

Benefits  of VPN or the Virtual Private Network

VPN or virtual private network is a way to protect not only the data you transmit through the network, also the data already on your computer against any kind of internet hijacking. Originally used by the corporate houses, the increased dependence over the internet has made VPN popular among the home networks too. The VPNs work in covering up your IP address. It is like a wall that is created behind which your IP address hides and the IP address that is shown could be from anywhere in the world. The people who know their way around the computers would not even log into a network that they are sure of being secure hence the importance in VPNs is further highlighted.

The VPNs do not make you anonymous, but just increases your level of privacy when you are online and it is really important to understand that anonymity and privacy are completely different terms. There is still some information left about you that could lead to the revelation of your true identity. Also the VPN provider does log into your information unlike what they said. You are not anonymous there otherwise how would they be able to provide you with the services such as a limit on the data to be used or the number connections and the services alike. Think about it.

But despite that fact, it is still very helpful to use a VPN in cases like when you need to bypass some internet filters and in cases where you need an IP address from a different country to get access to a particular website. It can also come handy when you need to share your files with a group of people online for a long period of time. And of course the basic service that the VPNs offer of online privacy has been one the greatest driving factor in order to use the VPN service.

It is just fair that if you need to be sure that the network that you use is a secure one, then the VPN providers also need to be sure that you are not someone who is trying to get away with a cyber crime. This is done by simple security checks like a biometric lock, or passwords, etc. it is like you log into an account where you fell down some information about you and the computer authenticates the information and once that is done, you are good to go ahead and use the VPN. Hence the security and privacy of both the user and the provider is maintained.

  • Safe strong Password– Selection of the password is one of the important security features. A difficult to assume password is synonymous with strong, secure password. This is the first step and the second one is, the package combination of letters, numbers and symbols should be used. Same password should not be used for every online service. This is the third one and the fourth and the final one is for at least every 90 days you need to change the password.
  • Security software protection- Security softwares may be of several types. These should be used to keep your computer safe. Firewall, Nortan and various types of antivirus programs are essential for computer security. We should remember that the configuration of antivirus and antispyware softwares is necessary for the purpose of update.
