# Prevent usage of 3DES keys \[New in Security Center 7.0\]

# Prevent usage of 3DES keys \[New in Security Center 7.0\] {#ariaid-title1}

Disable the use of 3DES static keys on your instance with a system property.
Use the glide.security.3des.static_keys_usable system property to disable the usage of 3DES static keys on your instance. This property should be set automatically by a scheduled job, the status of which can be
checked via the property glide.security.3des.removal_job_status. In cases where this property isn't configured to false, after the scheduled job runs and the status is
`KEYS_DEACTIVATED`, the scheduled job waits until this property is configured to false before proceeding with deletion of the 3DES static keys.

Ensure the glide.security.3des.static_keys_usable exists on the System Properties \[sys_properties\] table and is set to a value of false. Review [KB1704481](https://support.servicenow.com/kb?id=kb_article_view&sys_kb_id=78789f8347019a50f64de825126d43ad) for further information on 3DES deprecation.

| Attribute | Description |
|-|-|
| Configuration name | glide.security.3des.static_keys_usable |
| Configuration type | System Properties (/sys_properties_list.do) |
| Data type | Boolean |
| Recommended value | false |
| Default value | true |
| Fallback value | true |
| Category | [Stored cryptography](https://www.servicenow.com/docs/ZT6FughMXY7Ruy2MTjcQOg "This category focuses on the encryption of stored data. It encompasses several key aspects, such as employing established algorithms and cryptographic modules, ensuring the proper generation of pseudo-random values, implementing encryption based on data classification, and securely storing and isolating key material.") |
| Security risk | * Severity score: 5 * CVSS score: Medium * 3DES is deprecated, and the use of 3DES and 3DES static keys outside of temporary backwards compatibility isn't recommended. Continued use may lead to situations of sensitive information disclosure if a user were to obtain access to encrypted data. {#sc-prevent-usage-of-3des-keys__ul_ihv_dvg_1xb} |
| Functional impact | When set to false, there may be unlikely situations where code and data residing on the instance still relied on by 3DES static keys are now inaccessible. |
| Dependencies and prerequisites | None |
