Hi All

I did configuration command like in document. but the message it still show after scan again.

anyone have idea

for SSL/TLS to disable weak Algorithm-

set shared ssl-tls-service-profile web-gui protocol-settings auth-algo-sha1 no
set shared ssl-tls-service-profile web-gui protocol-settings enc-algo-3des no
set shared ssl-tls-service-profile web-gui protocol-settings enc-algo-rc4 no
set shared ssl-tls-service-profile web-gui protocol-settings keyxchg-algo-rsa no

I am reading on document it reccomend to do this anyone can reccomend command

thank you

Disable support for weak ciphers on the server. Weak ciphers are generally defined as:
· Any cipher with key length less than 128 bits
· Export-class cipher suites
· NULL ciphers
· Ciphers that support unauthenticated modes
· Ciphers assessed at security strengths below 112 bits
· All RC4 ciphers
· All CBC mode ciphers due to POODLE, Zombie POODLE, GOLDENDOODLE, 0-Length OpenSSL, and Sleeping POODLE
vulnerabilities
· All 64-bit block ciphers
· All ciphers using MD5 and SHA1 for cryptographic hash functions
The following ciphers supported by the server are weak and should be disabled:
· TLS_DHE_RSA_WITH_AES_256_CBC_SHA (0x39)
· TLS_DHE_RSA_WITH_AES_128_CBC_SHA (0x33)
· TLS_RSA_WITH_AES_256_CBC_SHA256 (0x3d)
· TLS_RSA_WITH_AES_128_CBC_SHA256 (0x3c)
· TLS_RSA_WITH_AES_128_CBC_SHA (0x2f)
· TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA (0xc014)
· TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA (0xc013)

Are you able to confirm in your network tab, under IPSec Crypto profile, that your objects do not include any of the above?

AES-GCM-128 and 256 with SHA256 (in my screenshot) will work.
