Apache 2.4 SSLLabs Test grade from "B" to "A/A+"



@ https://www.ssllabs.com/ssltest/


1. Chain Issues: Incomplete Chain



This means that your SSL/TLS certificate issuer (e.g. COMODO SSL) might not be ROOT CA,
so, there might be chains/nodes between your site and ROOT CA.
Modem browser will download them automatically,
yet SSLLabs test will highlight it out to warn you about this.

Solution: Try to Add CA Certificate File(SSLCACertificateFile) in ssl.conf will resolve this.

代碼:


#
# Assume you put all *CA*.crt file in /tmp/
#
$ ls -al /tmp/comodossl/*CA*.crt

-rw-rw-r-- 1 15:59 /tmp/comodossl/AddTrustExternalCARoot.crt
-rw-rw-r-- 1 15:59 /tmp/comodossl/COMODORSAAddTrustCA.crt
-rw-rw-r-- 1 15:59 /tmp/comodossl/COMODORSADomainValidationSecureServerCA.crt

$ cd /etc/apache2/ssl

$ cat /tmp/comodossl/*.crt > chain.ca.crt

$ vim /etc/apache2/sites-available/yoursite-ssl.conf

##### Add the following lines to make your chain complete
SSLCACertificateFile    /etc/apache2/ssl/chain.ca.crt


$ service apache2 restart


2. Chain Issues: Contains Anchor



This is OK, just a reminding and 100% harmless, no more grade-capped-to-B


3. This server accepts the RC4 cipher, which is weak. Grade capped to B.


代碼:

$ vim /etc/apache2/mods-available/ssl.conf

### Revise/Add the following lines

SSLHonorCipherOrder on
SSLCipherSuite "EECDH+ECDSA+AESGCM EECDH+aRSA+AESGCM EECDH+ECDSA+SHA384 EECDH+ECDSA+SHA256 EECDH+aRSA+SHA384 EECDH+aRSA+SHA256 EECDH+aRSA+RC4 EECDH EDH+aRSA RC4 !aNULL !eNULL !LOW !3DES !MD5 !EXP !PSK !SRP !DSS !RC4"

$ service apache2 restart


4. Clients that do not support Forward Secrecy (FS) Grade capped to B.



代碼:

$ vim /etc/apache2/mods-available/ssl.conf

### Revise/Add the following lines

SSLHonorCipherOrder on
SSLCipherSuite "EECDH+ECDSA+AESGCM EECDH+aRSA+AESGCM EECDH+ECDSA+SHA384 EECDH+ECDSA+SHA256 EECDH+aRSA+SHA384 EECDH+aRSA+SHA256 EECDH+aRSA+RC4 EECDH EDH+aRSA RC4 !aNULL !eNULL !LOW !3DES !MD5 !EXP !PSK !SRP !DSS !RC4"

$ service apache2 restart



5. Certificate uses a weak signature. When renewing, ensure you upgrade to SHA2.



代碼:

$ vim /etc/apache2/mods-available/ssl.conf

### Revise/Add the following lines

SSLHonorCipherOrder on
SSLCipherSuite "EECDH+ECDSA+AESGCM EECDH+aRSA+AESGCM EECDH+ECDSA+SHA384 EECDH+ECDSA+SHA256 EECDH+aRSA+SHA384 EECDH+aRSA+SHA256 EECDH+aRSA+RC4 EECDH EDH+aRSA RC4 !aNULL !eNULL !LOW !3DES !MD5 !EXP !PSK !SRP !DSS !RC4"

$ service apache2 restart



6. This server uses SSL 3, which is obsolete and insecure. Grade capped to B.




Just disable SSL2 & SSL3 since all modem browsers support TLS 1.1 & TLS 1.2;
This could prevent POODLE-bite as well.

代碼:

$ vim /etc/apache2/mods-available/ssl.conf

### Revise/Add the following lines
SSLProtocol All -SSLv2 -SSLv3


$ service apache2 restart

SSLLabs Test "A" to "A plus / A+"




Later, you could enable "Strict-Transport-Security"

enable enlist yourself to "HSTS preload",

Then you are likely to step in to A-Plus in SSLLabs test!
@ https://www.ssllabs.com/ssltest/

If you can't achieve all sub domains,
just remove "includeSubdomains; preload"

代碼:

$ a2emod headers

$ vim <your SSL site config path>

    <IfModule mod_headers.c>
        Header always set Strict-Transport-Security "max-age=31536000; includeSubdomains; preload"
    </IfModule>


$ service apache2 restart
