Wifi security for home and office network for information security

 

We in the world of technology, using internet through Wifi access in personal and public area.

Information security and data privacy is big concern now for everyone because we do not know how and from where our information may leak and misuse.

Wi-Fi become essential as all family members are using it for internet access for multiple reasons

 1.  What is router, gateway?

The active device which bridge your access and internet cable (service provider). The router could be combine equipment with wireless (Wi-Fi).

 2. Why router is critical device?

Router, plays a role which is managing your internet access with security and restriction as well. Hence if there is any loophole that may leak your data and information. Hacker may easily steal data or misuse internet facility.

 

3. Placing of router, gateway in house and office

One of the biggest safety point as your router physical location must be safe and hidden. To avoid any physical damage, hard reset and tempering of the device, power or its cable etc.

 

4. Default password change

Next, most of the times it is observed that after initial installation and configuration people do not change default password which is very vulnerable and threat for router access by hackers.

 

5. Default ip-address change

OEM has typical setup and ip address for setup and easy installation; everyone knows the default ip address because it’s part of admin guide itself. Therefor default ip address should be changed and

 

6. Hide identity of Wifi

SSID (Wi-Fi identify) is visible name of internet to which you are connecting devices. SSID should be hidden means it should not be broadcasting. Visible can be attacked and hidden will not be known. Hidden SSID will make you connect Wi-Fi manually that is one pain for first time setup, after that your device connection itself from next connection attempt.

 

7. Do Not use common name to get identify- that’s your router

Your device name should be such that it will not reveal your identity. Like if your name is Mike Goldman so you should not keep Mike or Goldman in router’s identity.

 

8. MAC address filter and restriction

Router allow you to filter MAC address which restrict other to get into network. It is one of the good practice for network security and information security.

 

9. Strong password

After successful configuration for the first time you should immediately change password. Keep password strong means at least 8 to 14 length of complex password.

10. Wifi protocol – WPA

There are three security programs which support by Wi-Fi routers. They are WPA, WPA2 and WPA3 you can choose one out of these. Higher WPA program is better.

 

11. Off device when not in use

In general observation, people keep their router, Wi-Fi dongle ON which may attract cyber-attack and attempt for Wi-Fi security break because of its availability.  Its meaning is when not required or going out you should switch off Wi-Fi devices, except CCTV cameras.

 

12. Disable remote access of router

For remote troubleshooting by default router’s access from out to inside traffic is allowed through multiple ports which is not safe hence it must be disabled after success configuration, installation.

 

13. Firmware & software update

It is recommended to keep your device upto date like router, computer, laptop and mobile, these are client device and any vulnerability may harm the systems.

 

14 .Keep firewall ON to devices, router

Firewall safety is essential nowadays because it always keep you protected from external attacks and unwanted harmful internet traffic. Firewall could be part of anti-virus also.

 

15 .Client devices update for patches – security and critical patches

Devices like Computer, Laptop and mobile etc which are client for Wi-Fi access should be updated regularly and specially all critical and security patches should be applied.

 

16. Office premise protection

If Wifi is controller based, then it must be MAC filtered and integrated with DHCP for better control. Extra authentication layer like AD integration, RADIUS server based login will make environment more security and robust.

Rogue AP should be avoided as that become weak entry points for data leakage and information theft.

Be Smart, Be Safe

How to protect your (PII) personal identifiable information?

"We share information everywhere as we want to gather information from everywhere"

 

Many of us unknowingly share personal identifiable informationalso known as PII to those who are not concern with information security or there is chance of data leakage or data theft.

Data and personal information is critical to if break, crack and reset, unlock your secret reveal for banking, financial and assets. Safeguard your information from hacking, information leakage. PII protection is part of information security.

 

What are PII, examples:

1.    Name, address, SSN, date of birth, phone number, email id

2.    Financial information, location, your parents name

3.    Biometric data – fingerprint, retina info

4.    Medical, education, employment records

 

Be careful and conscious while sharing data to agencies, consider below area where we generally share without thinking it and we attest also, few examples are.

1.    Being candidate for interview – full names with address

2.    In resume or CV also put date of birth as (mm/yyyy) that is enough – like January 1991.

3.    Opening bank account

4.    Mall, petrol pump and restaurant visit for better deal or for some prizes

5.    Education class form filling

6.    Online information sharing on open forum etc.

7.    Sharing information for driving license, passport number, Aadhar number, PAN number, social security number (SSN)

 

How to protect PII

Share information in smarter ways

1.  Always put purpose and recipients name while sharing (like for Citibank, for account opening, after that you only sign on document) – on every single paper.
2.  Always put expiry date while signing documents – valid upto 05/July/2020
3. Keep date and time and purpose inside of document (not outside, at blank space), protect from to be scanned and cropped.
4. Cross sign documents so signature prevail on inside area of document.
5. Don’t reveal mother’s name into unwanted forms it will help hackers to crack your OTP, banking password reset etc.
6. Never disclose or share CVV number for debit and credit cards.
7. Limit yourself on social media with PII information.
8. Don’t allow your phone to read SMS automatically, malicious apps will read OTP as well.
9. Don’t share sensitive information to young children; they may disclosure it.

 

Here I suggest that “Not sharing, unfolding is your PII protection; Be Smart, Be Safe.
