1.6 Product Security
eA680-950 security includes network security and application security. Application security
includes wireless security and OM security.
1.6.1 Network Security
eA680-950 network security uses Secure Sockets Layer (SSL) and Hypertext Transfer
Protocol Secure (HTTPS).
SSL
The SSL protocol is a security connection technology for the server and client. It provides a
confidential, trusted, and identity-authenticating connection to two application layers. SSL is
regarded as a standard security measure and has been widely applied to web services.
Identity authentication
Identity authentication checks whether a communication individual is the expected
object. SSL authenticates servers and clients based on digital certificates and
user/password. Clients and servers have their own identifiers. The identifiers are
numbered by the public key. To verify that a user is legitimate, SSL requires digital
authentication during data exchange in the SSL handshake procedure.
Connection confidentiality
Data is encrypted before transmission to prevent data from being hacked by malicious
users. SSL uses encryption algorithms to ensure the connection confidentiality.

Data integrity
Any tampering on data during transmission can be detected. SSL establishes a secure
channel between the client and the server so that all the SSL data can reach the
destination intact.
HTTPS
For the eA680-950, the OM TCP applications can use SSL. HTTP over SSL is generally
called HTTPS. HTTPS is used for connections between the NMS/WebUI and eA380. SSL
also uses the digital certificate mechanism.
HTTPS provides secure HTTP channels. HTTPS is HTTP to which SSL is added, and SSL
ensures the security of HTTPS.
1.6.2 Application Security
eA680-950 application security includes wireless security and OM security.
Wireless Security
eA680-950 wireless security includes authentication, air-interface data encryption, and
integrity protection.
OM Security
OM security includes user authentication, access control, OM system security, and software
digital signature.
User Authentication and Access Control
User authentication and access control are implemented for users to be served by the eA380.
The objective of authentication is to identify users and grant the users with proper permission.
The objective of access control is to specify and restrict the operations to be performed and
the resources to be accessed by the users.
OM System Security
OM system security includes software integrity check.
In the original procedure for releasing and using the software, the software integrity is ensured
by using cyclic redundancy check (CRC). CRC can only prevent data loss during
transmissions. If data is tampered with during transmissions, a forged CRC value will be
regarded as valid by the CRC. Therefore, the receive end cannot rely on the CRC to ensure
the consistency between the received data and the original data, adversely affecting the
reliability and security for the software.
Software integrity protection implements the Hash algorithm or adds a digital signature to
software (including mediation layers and configuration files) when releasing software, and
then uploads software to the target server or device. When a target device downloads, loads,
or runs software, the target device performs the Hash check or authenticates the digital
signature. By doing so, software integrity protection ensures end-to-end software reliability
and integrity.
Software integrity protection helps detect viruses or malicious tampering in a timely manner,
preventing insecure or virus-infected software from running on the device.
Digital Signature of Software

A digital signature of software is used to identify the software source. It ensures the integrity
and reliability of software.
When software is released, its digital signature is delivered with the software package. After
the software package is downloaded to an NE, the NE verifies the digital signature of the
software package before using it. If the digital signature passes the verification, the software
is intact and reliable. If the verification fails, the software package is invalid and cannot be
used. Figure 1-5 illustrates the principles of a software digital signature.
Figure 1-5 Digital signature of software
Before a software package is released, all files in the software package are signed with
digital signatures. That is, after a message digest is calculated for all files in the software
package, the message digest is digitally signed using a private key.
After a software package with a digital signature is loaded to an NE through a media
such as the software release platform, the NE first verifies the digital signature of the
software package. That is, the NE uses a public key to decrypt the digital signature and
obtain the original message digest. Then, the NE recalculates the message digest and
compares the new message digest with the original one.
−If the two message digests are the same, the software package passes the
verification and can be used.
−If the two message digests are different, the software package fails the verification
and cannot be used.
The public key used to decrypt digital signatures is stored in the secure storage area of an NE
and cannot be queried or exported.

the configuration, restarting and updating the DAU, and restoring the DAU to its default
settings. For details, see the web UI online help.
The default web UI login user name and password are admin and admin, respectively.
You can change the login password on theweb UI.
Internet Explorer 7.0 and a later version is recommended, because Internet Explorer 6.0 uses the SSL3.0
protocol that contains vulnerabilities.
To improve security, change the default password at your first login and regularly change the password.
A password must meet the following rules:
A password consists of 8 to 15 characters.
A password contains at least three types of characters of the following:
−Lowercase letter
−Uppercase letter
−Digit
−Special characters, including the space character and the following:
`~!@#$%^&*()-_=+\|[{}];:'",<.>/?
A password cannot be the user name or the reverse order of the user name.
A password cannot contain more than two consecutive characters that are the same (for example, 111
is not allowed.)
By default, the function to remotely log in to the DAU web UI over HTTPS is disabled. The
remote web UI functions the same as the local web UI.
The maximum number of WebUI login attempts is three.After three login failures, the WebUI login
page is locked and willbe unlocked after one minutes. The lockingduration is incrementedby one
minute each time the WebUI login page is locked later.
When the WebUI login password is forgotten, contact thedevice agent or maintenance center to
