Attack method called DDoS that disturbs network services
I'm retired now, but I've got some information processing-related qualifications, and I don't want to forget the knowledge I've gained. So I'm going to look through the information on free news sites.
In September of last year, there were cyberattacks on multiple public institutions.
The culprit of this incident seems to be overseas, and it seems that it will go into a labyrinth as it is, but the National Police Agency has announced an interim report. It seems that the intention is to call attention to cyberattacks on the Hiroshima G7 summit to be held this month.
The countermeasures against DDoS attacks released by the National Police Agency are carefully described. However, I think that only those who have learned network technology can understand this.
DDoS attack is a word that often appears in information processing tests, and I remembered the SYN flood attack in it. However, I learned from the this article that there are several variations of DDoS attacks. I'm impressed that attackers can come up with various tricks. I want them to use that energy for more useful things.
However, in order to carry out a DDoS attack of any kind, it is necessary to infect a significant number of devices connected to the network with a BOT.
Inadequate settings for these devices increase the risk of BOT infection. This is one such example.
It is impossible to eliminate the possibility of BOT infection from all devices in the world. An attacker can start an attack by instructing the bot. This is one of the 21st century crimes.
Denken and Frielen, who did not give up after all, defeated the formidable Mahato, but enemies still appear after that. Similarly, as long as BOT infections occur, the battle will never end.
As public information provided by the National Police Agency states, DDoS attacks cannot be prevented, but measures can be taken to reduce the damage. However, it is labor intensive and costly. At the cost of the convenience of having Internet services available at all times.
