AWS Elasticache Jedis using credentials - jedis

Question

I need to connect to a redis instance in my Elasticache. As I understand from Amazon Elasticache Redis cluster - Can't get Endpoint, I can get the endpoint from this.
Now suppose I get the endpoint and I use this endpoint to create a JedisClient(Since I use java) then How do I provide the AWS IAM credentials?
I am going to secure ElastiCache using IAM policies. How do I ensure no other application connects to this redis?

static AWSCredentials credentials = null;
static {
try {
//credentials = new ProfileCredentialsProvider("default").getCredentials();
credentials = new SystemPropertiesCredentialsProvider().getCredentials();
} catch (Exception e) {
System.out.println("Got exception..........");
throw new AmazonClientException("Cannot load the credentials from the credential profiles file. "
+ "Please make sure that your credentials file is at the correct "
+ "location (/Users/USERNAME/.aws/credentials), and is in valid format.", e);
}
}

public LettuceConnectionFactory redisConnectionFactory() {
AmazonElastiCache elasticacheClient = AmazonElastiCacheClientBuilder.standard().withCredentials(new AWSStaticCredentialsProvider(credentials)).withRegion(Regions.US_EAST_1).build();
DescribeCacheClustersRequest dccRequest = new DescribeCacheClustersRequest();
dccRequest.setShowCacheNodeInfo(true);
DescribeCacheClustersResult clusterResult = elasticacheClient.describeCacheClusters(dccRequest);
List<CacheCluster> cacheClusters = clusterResult.getCacheClusters();
List<String> clusterNodes = new ArrayList <String> ();
try {
for (CacheCluster cacheCluster : cacheClusters) {
for (CacheNode cacheNode : cacheCluster.getCacheNodes()) {
String addr = cacheNode.getEndpoint().getAddress();
int port = cacheNode.getEndpoint().getPort();
String url = addr + ":" + port;
if(<ReplicationGroup Name>.equalsIgnoreCase(cacheCluster.getReplicationGroupId()))
clusterNodes.add(url);
}
}
} catch (Exception e) {

LettuceConnectionFactory redisConnectionFactory = new LettuceConnectionFactory(new RedisClusterConfiguration(clusterNodes));
