How To Stop Enemy Movement During Its Attack Animation

I have an enemy and when it's doing its attack animation I would like it to stop moving and rotating until the animation finishes. I'm sure it involves setting the force to 0 and whatnot but I'm unsure how to phrase the coding in a way that achieves this effect

 public class Chase : MonoBehaviour {
 
     public Transform player;
     public CapsuleCollider cc;
     private Animator anim;
     private Rigidbody myRigidbody;
     private Vector3 moveDirection;
     public Collider attack;
     public Slider healthbar;
     
     void OnTriggerEnter(Collider attack)
     {
       if (attack.gameObject.tag == "PlayerAttack") {
      
           healthbar.value -= 20;
           anim.SetBool("IsInjured", true);
          }
          
       
      }
 
     // Use this for initialization
     void Start()
     {
         anim = GetComponent<Animator>();
         myRigidbody = GetComponent<Rigidbody>();
         
         cc.enabled=false;
     }
 
     // Update is called once per frame
     void Update()
     {
 
         moveDirection = Vector3.zero;
         
 
         if (Vector3.Distance(player.position, this.transform.position) < 4)
         {
             Vector3 direction = player.position - this.transform.position;
             direction.y = 0;
 
             this.transform.rotation = Quaternion.Slerp(this.transform.rotation,
                                         Quaternion.LookRotation(direction), 0.3f);
 
             anim.SetBool("IsIdle", false);
             if (direction.magnitude > .8)
             {
                 moveDirection = direction.normalized;
                 anim.SetBool("IsMoving", true);
                 anim.SetBool("IsBiting", false);
                 anim.SetBool("IsInjured", false);
             }
             else
             {
                 anim.SetBool("IsBiting", true);
                 anim.SetBool("IsMoving", false);
             }
 
 
         }
         else
         {
             anim.SetBool("IsIdle", true);
             anim.SetBool("IsMoving", false);
             anim.SetBool("IsBiting", false);
         }
         
          if (healthbar.value <= 0){
             anim.SetBool("IsVulnerable", true);
             }
          else
          {
             anim.SetBool("IsVulnerable", false);
          }
 
         
     }
     public void ActiveCollider(int active){
     
         if (active == 0)
             cc.enabled = false;
         if (active == 1)
             cc.enabled = true;
             }
     public void VulnerableRegain(int active){
     
         
         if (active == 1)
             healthbar.value += 60;
             }        
     
     
     void FixedUpdate()
     {
         myRigidbody.AddForce(moveDirection * 70f);
     }
     
 }
