# 7.4 Ensure directory in context.xml is a secure location (Manual)

## Description

The `directory` attribute tells Tomcat where to store logs. It is recommended that the location referenced by the `directory` attribute be secured.

## Rationale

Securing the log location will help ensure the integrity and confidentiality of web application activity.

## Audit Procedure

Review the permissions of the directory specified by the `directory` attribute to ensure the permissions are `o-rwx` and owned by `tomcat_admin:tomcat`:

```
# grep directory context.xml
# ls -ld <log_location>
```

## Remediation

Perform the following:

1. Add the following statement into the `$CATALINA_BASE/webapps/<app_name>/META-INF/context.xml` file if it does not already exist.

```xml
<Valve className="org.apache.catalina.valves.AccessLogValve"
directory="$CATALINA_HOME/logs/"
prefix="access_log" fileDateFormat="yyyy-MM-dd.HH" suffix=".log"
pattern="%h %t %H cookie:%{SESSIONID}c request:%{SESSIONID}r %m %U %s
%q %r"
/>
```

2. Set the location pointed to by the `directory` attribute to be owned by `tomcat_admin:tomcat` with permissions of `o-rwx`.

```
# chown tomcat_admin:tomcat $CATALINA_HOME/logs
# chmod o-rwx $CATALINA_HOME/logs
```

## Default Value

Does not exist by default
