This time's theme is about "website tampering."
We will describe risks, patterns, and countermeasures for web tampering.

there are many possible risks, including the following:

• Leakage of confidential information

• Liability, suspension of trading
• Complaints and apologies from related parties
• Decline in corporate brand power
• Decrease in company sales
• Website closed
• Previous web promotion expenses went to waste.
• Virus infections such as malware (dangerous sites that attack site visitors, secondary damage)
• Penalties from search engines (blacklist registration, decline in SEO), etc.

Measures against website tampering

occurs
when a website's vulnerabilities are attacked or In particular, with regard to website vulnerabilities, as systems have become more complex in recent years,
the probability of vulnerabilities tends to increase accordingly.

As a way to reduce the risk of website tampering, it is effective to introduce IPS/IDS/WAF as a proactive measure, but
it is difficult to prevent 100% attacks on the website with this alone, so it is
also recommended to introduce website tampering detection tools. I recommend it.
This facilitates early detection of website tampering and enables prompt website recovery.

Website tampering check

As a tool for checking web tampering, we recommend
"Gred" automatically monitor website content,
send alerts when problems occur, and generate detailed reports.
