Funny things

My pet theory is there should be FUN when you are doing anything.

Every time I opened my laptop, its’ Network interface didn’t work. There are two options to use Internet on it. The first is waiting until connected the Internet automatically, but it’s take so long time, So I usually chose the second option. The second option is able to reduce the waiting time by turning off/on Network interface by using a batch script below.

netsh interface set interface Wi-Fi DISABLED
netsh interface set interface Wi-Fi ENABLED
netsh interface ip show interface
ping -n 10 8.8.8.8

However, I didn’t execute the batch script on the offline laptop today. Because I can wait until I use the Internet while playing a quit simple game on Chrome browser as below. I found FUN.

Sometime, I envy what Google do that. I really want to find funny things in Computer Security.

Security is a persistent

A security breach made me to be more thinking what OR how is a practical security. I think it’s important not only to protect aginst attack but also to prevent it. However we can easily lean to the former because it’s take more time and money also than the latter. The other hands, the prevent action is effective and efficent in terms of security.

There is a brute force attack in order to find a password of a target user. We use just six number as a verification code like OTP. It means that an attacker can know a password in maximum 1,000,000 times in theory. It just takes 14 minute unless there is threshold of PPS.

Anyway we can protect the attack by block the IP addresses used in it. But attacker keep to trying to attack with change the IP address. After all, the prevention is not property prevention.

We need to know why/how did the attacker attack in order to cut off the root cause. That is what we call the user profiling. But it’s not easy as you know. We are lack basically about an attacker who is hidden like a rootkit.

We already know that is. So we must make persistent effort to follow up the attacker as if we are waiting rainbow.
